After losing a shoe and seeing a street sign has gone missing, high school student Violet Bookman begins an Instagram account to try to document everything strange that's disappeared. When she's not riding around town on her bicycle, she likes to spend time with her twelve-year-old neighbor, Nanako, a cellist who invents her own board games.

But when Nanako's cat, Mr. Business, goes missing, Violet searches all over town, from British Soldier Field—where the British soldiers once disappeared in the woods in the 1760s—to the envelope factory to the garbage dump to the clock tower.

On her search, Violet meets Bruno Ellis, an enormous Streets and Sanitation worker, who may have been a professional wrestler and whose career may have come to a tragic end. His cat has also gone missing.

She also meets Ms. Holly Peterson, the new 3rd grade teacher, who sometimes wanders alone at night, looking for the ghost of her younger brother.

Along the way, Violet discovers that a corporation named New Tomorrow Industries is building a gigantic hole on the outskirts of town.

Violet also thinks she sees a peacock in the woods but isn’t sure. She also discovers that someone is leaving messages in code on various buildings in town stating, “Everything Begins at the End.” In discovering one of these hidden messages at the clock tower, she realizes the hands on all four faces of the clocks on the tower appear to tell different times.

Violet meets Officer Ron Dublowski, a police officer who has realized, a little too late, that he would much rather be a music producer than a cop. Ron's dream is to attend the Randy Simms School of Music in Columbus.

Tragically, this week ends with the collar belonging to Mr. Business, the beloved pet Violet has been searching for, being found by Officer Dublowski. Nanako's family holds a funeral while Violet refuses to give up hope.

Violet finally learns the name of the strange music she's been hearing in the woods, “Abime des oiseaux…” She visits Ms. Twombley at the Question Mark Public Library, looking for answers. Ms. Twombley remembers that there is a book that mentions a British soldier also hearing music in the woods.

While searching for the source of the music, Violet and Nanako find teeth that seem to belong to several pets in the woods. Where will this strange clue lead her? And what, or who, will disappear next?

Violet gives a presentation about everything that has disappeared in town at the library. However, no one but Ms. Twombley, the librarian, showed.

With Ms. Twombley's help, Violet is able to locate a copy of the musical composition, Quatuor pour la fin du temps, "Quartet for the End of Time," which seems to be the music she has been hearing. Inside is a note that reads, “Music is the key to opening the shaft of the abyss.” First she tries playing the music at the enormous hole that New Tomorrow Industries is digging and sees a ghostly figure. Then she speaks with Ms. Peterson, the third grade teacher, who says she has been dreaming about the ghost of a British soldier.

Meanwhile Officer Ron Dublowski has been facing his own troubles. Coming back several days late from a CPR class outside of town, Ron's wife Beth returns but tells Ron she wants a separation. Overcome with grief, Officer Ron drives out to British Soldier Field, where he encounters Violet who has gone there to play Quatuor pour la fin du temps. Instead she plays a Japanese Breakfast song for him and the two begin to feel more hopeful, in spite of all the disappearances.

Finally, Violet gets a clue from Ms. Twombley who remembers a newspaper story about the remains of a British soldier being recovered when the Question Mark video store was being built. Where will this latest clue lead and what strange new mystery might she uncover at Question Mark Video?

Following Ms. Twombley's advice, Violet visits the Question Mark video store and meets disaffected video clerk, Dash Holland, twin brother of Parker Holland, who claims to have seen the ghost of the British soldier in a video from the 90s.

Violet rents the video and watches it and receives an eerie message from a ghostly figure that warns, “Beware the endless circle.” Violet first tries exploring “the infinite circle,” a burial mound built by the Adena or Hopewell people in 1000 BC. There she sees a strange light. When she asks Officer Ron about the light, he warns her to stay away from that area as various local criminals, including the Towns brothers, have been known to use that part of the woods for illicit activities.

At the same time, Officer Ron is struggling to manage his duties as a parent and police officer now that he and his wife Beth are separated.

Following a clue from a map she found in one of Reginald Willey's books, Violet discovers a place in the woods called "Le Circuluis Nonfinis," which Ms. Twombley helps her translate as "The Endless Circle." There she and Nanako find the peacock Violet spotted weeks before and realize there is a tag on its foot that says, "Foreverland Pet Refrigeration." Back at Nanako's, the pair discover there is a code in the Foreverland website that mentions an accident involving time. Where will this new clue lead the intrepid Violet?

Violet investigates Foreverland Pet Refrigeration and finds the building has been boarded up. Feeling overwhelmed by the escalating circles of overlapping mysteries, she breaks down. Ms. Peterson appears just in time to remind her that there are some challenges we choose, while other challenges choose us.

The next day, the ice cream cone statue in front of Mr. Freeze-E goes missing and the whole town is shaken, especially Officer Ron, who is facing the end of his marriage and this latest disappearance, feels equally overwhelmed with both.

On Monday, Violet returns to “le circuluis nonfinis,” or the hidden meadow, to search for the peacock. This time she discovers the peacock's tag has a name on the other side: “T. Zisk,” which suggests the mayor's deceased husband was once the owner of the mysterious peacock. Violet follows the clue to the mayor's office and leaves a note for her. Later that day, Violet finds a letter from Mayor Zisk, warning her that both of them will be in danger if Violet keeps searching for the truth. Undeterred, Violet returns to the hidden meadow and encounters a strange person in a beekeeper's outfit, photographing a number of circles that have been drawn on the trees in chalk. Violet wonders if these circles are the endless circle she has been warned about.

While searching for the peacock in the woods, Violet meets Everard Bright, a professor from Cincinnati studying cults, who warns that members of the Order of the Arranger, a cult from California, may be living in town. Violet and Bruno continue to search the woods for the missing pets and come upon a strange discovery: in the hidden meadow, several floating purple lights appear. When Violet returns to her bicycle, she finds someone has let the air out of her tires.

Ron continues to struggle to balance his life as an officer of the law with being a single father. That balance isn't helped when Miss Mozart, a local celebrity cat, goes missing.

Searching for answers about the purple lights in the woods, Violet begins to suspect that two workers at Mr. Freeze-E Ice Cream may be linked to the Order of the Arranger after one of the workers puts several suspicious bags in the back of a black van and drops them off at the town dump.

When Violet's dad reads her grades for the final quarter, he asks her to please let her pursuit of the truth of the disappearances in town go. Violet refuses, and instead finds an odd code on the Order of the Arranger website. Her next step is to see if she can make a connection between the suspicious bags, the code, and the suspected cult members at Mr. Freeze-E.

Finally solving the coded message from the suspicious workers at Mr. Freeze-E’s, Violet is heartbroken to learn that the body of one of the missing cats in town has been discovered dead and missing its head. Although it is not Mr. Business, it’s soon revealed the cat belongs to Department Streets and Sanitation worker, Bruno Ellis. Together, Violet and Bruno confront the suspected cult member who claims not to have been involved in the cat’s demise, although he warns of something frightening living out in the woods.

At Question Mark Foods, Officer Ron runs into his estranged wife, Beth, and the two have a much-overdue conversation about the struggles they face in their marriage.

On Thursday, Violet discovers the two strange workers from Mr. Freeze-E have quietly disappeared and that Tanner Pratt, elderly citizen, has offered a warning about the future of the town in his recent presentation. Finally, while doing research at the library, Violet makes the joyous discovery that Ms. Twombley is pregnant.

Searching for clues regarding what might be living out in the woods and causing things to disappear, Violet follows the white pollen that has been floating all over town and discovers several scientists from the Experimental Crop Station in gas masks and hazmat suits have taped off a large section of the woods. Returning to the woods to find out what the scientists might be hiding, she runs into Ms. Peterson who shows her a large purple light glowing from underground.

Using these clues, Violet discovers a report from Nanako’s dad, Dr. George Yakamoto, describing how an enormous fungus, Armillaria Quaestio, has been living in the forest, hidden for thousands of years. The report includes a map and also suggests the fungus may be eating insects and small animals.

Meanwhile Officer Ron makes a strange discovery of his own, tracking down the suspicious black van used by the suspicious Mr. Freeze-E employees to the Question Mark Motel. There he finds both employees have gone missing, leaving piles of white dust and a part of a coded message.

Finally, Violet follows the map of Armillaria Quaestio through the woods and meets Dr. Allison Andrews, who says that the fungus is entirely harmless but also suggests something called Cucumis Quaestio may have escaped from the Experimental Crop Station and might be responsible for the disappearances in town.

Violet begins working at the Question Mark Public Library and uses that time to learn all she can about the strange purple glow in the woods. After work, she rides out to the woods and plays a familiar piece of music on her phone and Mr. Business appears. She pulls him to her chest, but there is a flash of purple light that immediately frightens Mr. Business away.

Violet returns to the woods the next night and plays the music again but this time a large, floating purple orb of light appears and attacks her.

Officer Ron is deeply upset to discover the town’s fireworks have been stolen. The next day he runs into his estranged wife, Beth, and finally asks when she plans to return home. Eventually she reveals that she needs to become a new person without him and will not becoming back. Emotionally reeling, Ron attends a meeting of the Circle of Concerned Families and Friends, looking for meaning and purpose.

Violet, still recovering from her confrontation with the purple light, receives a cryptic message from Mayor Zisk. Unsure how to proceed, Violet makes a connection with a young boy named Quentin Quinn at the library. Violet sees the purple light near the garbage dump, uncertain if it may be responsible for all the town’s recent disappearances…

While searching for the floating purple light, Violet speaks with Officer Ron and learns both of them live with hearing loss. Violet finds the purple light menacing two girls and chases it off, coming to recognize that the strange creature seems to be attracted to certain kinds of music.

Before she can warn the rest of the town of the danger the purple light poses, six-year-old Quentin Quinn goes missing. Violet learns that the boy had been trespassing at Question Park and petting zoo with his older brother and his friends, and may have been dared to enter the House of Dazzling Glass. But it appears Quentin never came out.

Violet rushes to the abandoned amusement park) and enters the House of Dazzling Glass, only to exit a day later, with no sense of how much time had actually passed, which leads to a terrible fight with her father.

While at work at the library, Violet learns the mayor’s deceased husband was co-owner of the park at the time of his death, and held a number of other strange investments as well. She also discovers someone named Marcy Towns disappeared inside the House of Dazzling Glass in 1998. When Violet confronts Marcy, she finds out it was only a hoax and that Marcy hid in a cave in the woods for two days in order to sell her story to the newspapers.

After several days without any clues or leads to the missing boy’s whereabouts, Chief of Police Gus Holt calls in the FBI from nearby Columbus, prompting a sense of escalating fear and imminent danger.

Following a clue from Marcy Towns as to the whereabouts of Quentin Quinn, Violet searches the Ghost Gap, a little-known cavern deep in the woods. Instead of finding the missing boy, Violet discovers the strange purple light hiding at the bottom. Sensing the light is weak, Violet offers the creature her father’s flashlight which it quickly consumes.

The next day, a fire engulfs the New Tomorrow particle accelerator construction site. Violet rides over and uncovers a message from the Order of the Arranger, presumably warning of the approaching end-times. Officer Ron and Chief Holt suspect the fire has been started using the town’s missing Fourth of July Fireworks, though no arrests are made.

At the Question Mart, Violet meets FBI Agent Adam Oberman, a young investigator who confesses his ambivalence about working for the FBI. Admitting he would rather have pursued a life in musical theater, Violet feels a connection and decides to tell him everything she’s learned about the town.

With help from Ms. Peterson, Violet records a Morse code message in the woods, which may have been sent from Quentin Quinn. Decoding the message, Violet learns it is a clue involving the missing library book, Moonlight Woods. At the library, she finds a digital copy, which leads her in search of a crystal cave somewhere in town. What danger will this latest clue lead her to?

While searching for Quentin Quinn, Violet follows the clue in the book Moonlight Woods out to an abandoned pyrite mine in the woods, only to be terrified by the appearance of an unfamiliar face. Returning the next evening with Bruno Ellis, the pair discover a backpack belonging to the missing boy. After hours of questioning by the FBI and QM Police, Violet is released only to find out that New Tomorrow Industries is planning a test of their particle accelerator on Saturday the 29th. She also learns that the Order of the Arranger is involved in some kind of struggle against New Tomorrow and that confrontation now seems all but inevitable.

Meanwhile, Officer Ron finally works up the nerve to sit across from Ms. Holly Peterson at Bingo but is unable to make his feelings known. Then, while enjoying his day off by watching an old favorite on TV, he hears a strange voice coming from his television.

After missing several days of work, Violet is fired from the library but receives a message left on her bicycle, telling her everything will be okay. Returning to the library to apologize to Ms. Twombley, she has a strange interaction with Tanner Pratt, who suggests she is the key to solving the town’s many disappearances. How will the town be changed by the approaching confrontation between the past and the future? And how will Violet finally make the invisible secret hiding in the woods visible?

After searching the woods for clues of Mr. Business and Quentin Quinn, Violet returns home and finds her father playing “Afraid,” one of her mother’s favorite songs on piano. Violet’s father informs her that will be going to Cleveland on Monday to visit her grandmother for a few weeks. She protests and runs to her room where she receives a mysterious call from Agent Oberman, summoning her to the woods the following afternoon.

At the woods, Agent Oberman tells her he believes that things are indeed disappearing in town and shows her an evidence bag that once contained Quentin Quinn’s shoes. Just then New Tomorrow Industries tests their particle accelerator. The sky is momentarily frozen and turns pink. Returning to town, Violet finds all the clocks have stopped.

Before leaving for Cleveland, Violet goes back to the woods once more and plays a recording of her best friend Nanako on the cello. Mr. Business finally reappears! Violet follows him deeper to the woods and, at the endless circle, Violet recalls all the secret messages she has received so far. She decides to play her mother’s favorite song, “Afraid,” and a strange, circular, white light appears. She is able to quickly make a recording before it fades.

Meanwhile, Officer Ron learns that ex-con Judah Towns has been released from prison early and has joined the church group, The Circle of Concerned Family and Friends. When Ron asks the leader of the group, CM Waldorf, about this arrangement, Waldorf responds by suggesting men like Judah will be needed for some kind of upcoming confrontation. The next day, Officer Ron is suspended without pay for posting police business on social media.

After discovering a strange circular white light in the woods, Violet leaves Question Mark to visit her grandmother in Cleveland. Returning after three weeks, she considers the series of strange disappearances that have affected the town and is disappointed to discover Mr. Business and Quentin Quinn are both still missing. She also learns that the FBI has largely given up on the case.

Beginning her final year of high school, Violet notices her French teacher, Mr. Lefebvre, seems much more amiable and spots a mysterious love letter on his desk. After learning her best friend Nanako is leaving town to go to a music conservatory on the East coast, Violet decides to turn her full attention to finding the truth about the town’s disappearances. While visiting Gary Dublowski, she receives another message from Quentin Quinn, describing a town of missing things. Could this be the clue she’s been waiting for?

Meanwhile, Town Librarian Greta Twombley discovers that pages are missing from a book in the Reginald Willey Archive, and a code has been left in their place. Ms. Twombley is also having trouble with her pregnancy. The baby seems to disappear and reappear within her.

Finally, returning from a three week suspension for posting police business on social media, Ron Dublowski rejoins the Question Mark Police Department determined to be a new Ron and to let his feelings for Ms. Holly Peterson be known. Unfortunately, due to his lack of confidence and several calls to the police department for missing keys, Ron is unable to truly reinvent himself. What major event will it take for Ron to become the person he’s always been meant to be?

Violet begins her senior year of high school and discovers a piece of paper bearing a code belonging to the Order of the Arranger, a dangerous cult from California that is seeking to bring about the end of the world. Before she has time to make sense of this impending threat, the British statue from British Soldier Field goes missing, which leads to an argument between Violet and Officer Ron Dublowski.

The next day, Violet meets Iris, another high school senior who has just moved to town and who has a fascination with the occult. Violet explains everything she knows about the strange events in town and Iris enthusiastically agrees to help her solve the ongoing mystery.

After starting a new job at the Question Mark Car Wash, Violet receives a strange message in French, pointing her and Iris back to the white circular light in the woods. While searching for the light, they run into Professor Everard Bright who warns that the Order of the Arranger is looking for something similar, a void in time, a kind of portal to release the Arranger and bring about a new age of darkness.

Officer Ron, disillusioned by the disappearance of the British soldier statue, begins investigating a pair of footprints in the woods and, with his son Gary’s help, soon begins to suspect ex-convict Judah Towns may somehow be involved. But is Ron truly ready for the danger that may lay ahead?

Violet and Iris sneak into the Eastwood Circle pool and Violet receives another message in French, which sends them to visit the Infinite Circle, where they learn the white circle Violet saw may have existed for hundreds of years, even before the disappearance of the Hopewell people in 400 AD.

As Violet continues her investigation at the library, she is threatened by a masked member of the Order of the Arranger who demands to know the location of the opening to other dimensions. While continuing their search, Violet and Iris find a strange, lumbering man in the woods who drops a page written in French. With Agent Oberman’s help, they learn the page is actually from a Bible belonging to French missionary Jacques Blanchet and that Blanchet’s remaining letters are now in the trunk of a 1972 Chevelle that will be part of Friday night’s car contest. In order to learn the truth of the white circle, Violet and Iris must win the car in a battle of endurance.

Meanwhile Officer Ron keeps tabs on the Towns brothers while finally gaining the courage to go on a walk with Ms. Peterson. But a recent announcement from cult theorist Everard Bright may upend everything…

In the middle of Buck Walters’ car contest, an explosion momentarily interrupts the proceedings. Unwilling to let go of the car, Violet and Iris see the town’s water tower has collapsed. QM Police immediately suspect the involvement of the Order of the Arranger.

On Sunday, after losing the car contest, Violet learns of a bird named Pierre at Meow’s the Time pet store that speaks and writes in French. With Iris’ help, Violet follows a clue from Pierre to a strange-shaped tree in the Question Mark woods. Aided by Bruno Ellis, the three discover a long-buried diary from French missionary Jacques Blanchet that details the mysterious disappearance of the French colony in 1748.

Meanwhile, Officer Ron continues to get to know Ms. Peterson, taking her on a true crime tour of Question Mark, all the while trying to learn what the Towns brothers are doing out in the woods. While listening to CDs, he receives a message from Quentin Quinn who suggests a tree with old shoes may be a point of contact between the world of Question Mark and the world of missing things. Little does he know that Holly Peterson has seen the very same tree herself and is struggling to understand its meaning.

While looking for more evidence to the existence of the glowing white circle, or what Blanchet referred to as the void, Violet encounters the purple light monster. For a moment, the creature seems to recognize her and then floats away, leaving behind a nest of shiny objects, including an antique ruby ring, which Violet believes may have belonged to one of the missing French colonists.

Where will this latest clue lead?

Violet and Iris bring the ruby ring from the missing French colonist to Jock Reynolds and discover Elodie Reinhold is one of his ancestors. As a reward for solving this centuries-old mystery, Jock gives each of them a fighting kite and a few pointers.

The next day, Violet is approached by Dash Holland from Question Mark Video, who has an unsettling mystery of his own. The ghost of the British Soldier, which video store workers call Wheezy, has asked to speak to someone who knows how to talk to ghosts. Using Iris’ ouija board, Violet, Iris, and Dash discover that the ghost’s name is William Headley and that he was captured by the French after his entire regiment disappeared in the woods. Before being executed, he gave an jeweled hair comb shaped like a bird belonging to his fiancé to a French nun in the hopes that she would hide it. The ghost believes it is the hair comb that is keeping it trapped in the video store and asks the group to find it.

As Violet and Iris search for the comb, they learn that, along with Bruno Ellis, they are the new owners of the Upside-Down House, according to Buck Walters’ will, after solving the mystery of the French colony’s disappearance. Violet and Iris explore the strange house and find the jeweled comb in the basement among several boxes of other British artifacts. They return the hair comb to the video store and the ghost of William Headley vanishes and later turn over ownership of the house to the town historical society.

Meanwhile Officer Ron grows closer to Holly Peterson, showing her his favorite place in town, the garbage dump. Holly reveals that the ghost of her brother has appeared to her recently and that both of them are haunted by a tree full of old shoes that seem to appear and disappear. Ron catches an old episode of The Green Fog and wonders if the tree appears only when the moon is full.

Violet receives a message stuck in the spokes of her bicycle and she and Iris head to the endless circle where they meet Theophilus Willey, a descendent of town founder Reginald Willey, who has also been working to uncover the mystery of the circular light in the woods. With Violet and Iris’s help, the trio decode a passage from Willey’s writing and using several pieces of music, each with their own specific musical key, they are momentarily able to make the white light visible. Violet decides they must find a way to close the void for good. Theophilus mentions a musical composition his great-great-uncle was working on entitled Question Mark, OH, Question Mark which may be the answer.

After locating Reginald Willey’s unfinished musical composition, which he wrote as a means to close The Void once and for all, Violet enlists Nanako Yakamoto’s help to complete the song. Before playing the composition, they are joined by archeology student Patsy Elske and several other citizens including Bruno Ellis, Jock Reynolds, Dash Holland, and Ms. Twombley, who all take part in a commemoration of everything that has been lost in town from its earliest beginnings. Once the ceremony concludes, Nanako plays the completed melody, which everyone hopes will save the town from further disappearances.

Later that evening, Violet, Iris, and Nanako discover the song has had the opposite effect: The Void is now fully visible and does not go away. Violet calls Officer Ron for help. Once he arrives, he makes the critical decision to inform the rest of the town.

Within two days, ever-enterprising Mayor Zisk launches Visit The Void, turning the odd phenomenon into a money-making tourist attraction. Violet and Iris are shocked to find out the ploy actually works, as long lines of visitors come to town to visit the strange anomaly.

One day later, terror strikes the town as the Greenberg Yarn factory explodes and the sinkhole reopens, twice as large as before. Violet rides to the scene and sees a message from the Order of the Arranger, wondering how this fits into their plan of unleashing an otherworldly being intent on bringing about a new dark age.

Elsewhere, Officer Ron and Holly Peterson continue their search for the disappearing tree. While on duty, Ron witnesses an entire factory, complete with smokestacks, appear and then disappear and wonders what its connection to the odd tree might be.

While staring at the rubble of the yarn factory, Violet receives a phone call from Quentin Quinn in code, warning her that something terrible is coming and suggesting she speak to William Higgland Jr., owner of the video store and a former Order of the Arranger member. What devious scheme will Violet uncover?

After following the message from Quentin Quinn, the missing boy, Violet seeks out William Higgland Jr. and learns of the Order of the Arranger’s plans. Violet discovers a post complete with a map that seems to suggest that the Order intends to perform a ritual in order to release the Arranger, a ritual which may or may not include murder.

Violet looks for further clues and is attacked by three members of the cult. Q-eey, the floating purple light, saves her at the last moment. The next day Violet returns to thank the strange creature for its help and Dr. George Yakamoto from the Experimental Crop Station uses the opportunity to trap Q-eey and return it to the laboratory from where it escaped.

The next day, Violet is researching the crop station at the library when Ms. Twombley realizes she is going into premature labor and asks for Violet’s help. Driving her to the nearby town of Marietta, Violet is one of the first to receive the good news of Winnifred Twombley’s birth.

Meanwhile, Officer Ron continues to investigate the Order of the Arranger on his own, following several new arrivals in town, but without much luck. His relationship with Holly Peterson grows even closer as she shares with him several disturbing dreams she has had about a group of children trapped inside of a mountain. She tells him that she believes one of the reasons she’s come to town is to help these lost children move on.

Finally, with Professor Bright and Iris’ help, Violet finds the Order’s secret meeting place at the Question Mark Motel. There, in room 0, the trio uncovers several photographs, including one of Professor Bright and one of Violet, and a coded message, which suggest the ritual will take place on Saturday, October 14th, the day of the eclipse. Violet decodes the phrase “blood of the child” and worries it may refer to Winnifred Twombley or even herself. That evening, she is visited by the specter of Bill Twombley, who asks her to please watch over the child. But will Violet be able to keep the Order from completing their despicable task?

As the [solar eclipse unfolds above them, Violet and Iris learn a body has been discovered in the Question Mark Woods. A police report and announcement from Mayor Elizabeth Zisk confirm that car wash owner and town council member, Tom Childs, has been murdered. Due to his vacancy on the council, a special election is scheduled for November 7th.

Violet seeks out William Higgland, a former Order of the Arranger member, and learns that the next step in the cult’s plans is to seat the Seven Lords, whatever that might mean. Rushing to get answers from Professor Bright, Violet finds he has been attacked by the Order, after learning of their intention to fill the town council vacancy with one of their own members.

Owen Brandt, the conservative QM HS Assistant principal, immediately announces his intention to run and is soon followed by Gerald Ames, the mild-mannered librarian assistant, each with their own clashing visions for the town and its future.

Meanwhile, Officer Ron Dublowski and Ms. Holly Peterson look for answers regarding the increasingly strange dreams she is having. After one such incident, Holly reveals a burn on her wrist. Ron attempts to comfort her. Later, while watching an episode of The Green Fog, Ron wonders about the nature of ghosts in a conversation with his son, Gary, who suggests these supernatural beings might only be individuals trapped in time. Upon seeing ex-con Judah Towns, Ron decides to try to help the young man move forward from his own troubled past.

As Violet struggles to understand the Order the Arranger’s next steps, Ms. Twombley, the town librarian, asks Violet to watch baby Winnifred, warning Violet not to take her eyes off the baby. When Violet’s back is turned, the baby seems to disappear and then reappear. Violet finds a small piece of fabric in Winnifred’s hand, which immediately turns to dust. How might the baby’s strange condition fit into the ongoing disappearances and reappearances the town is now facing?

As the town continues to grieve the loss of Tom Childs, Violet and Iris uncover a ghostly factory, floating over the Question Mark Video Store and later near the Quantum Dynamic Solutions Eightcellerator construction site. Violet learns that Iris’ father Gavin is an avid amateur paranormal investigator who runs his own blog, dedicated to ghosts called Spirits of Ohio. Iris suggests that the apparition is connected to the Ames Rifle factory fire that claimed the lives of ninety-nine children in 1866. Gavin mentions that the ghosts of the factory speak in a language where past and future collide together.

Violet and Iris find the ghost factory in the Question Mark Motel, and along with Ms. Holly Peterson, they go inside, seeing a tree covered in burned clothes and shoes. As they delve deeper into the factory’s past, they learn that although the factory owners claimed no remains were ever found, other stories surrounding the appearance of ghostly children present a different possibility. In order to resolve this collision of past and future, Violet and Iris must find where the remains have been hidden. Soon a ghostly message from the children reveals that a compass will lead them to the answer.

Meanwhile, Officer Ron and Holly Peterson’s relationship continues to develop, as they share an intimate moment at the town dump. Shortly after, Officer Ron’s keys go missing. He spends some time riding his bicycle investigating town newcomers and sees Town Council candidate Owen Brandt vandalizing his competitor's yard signs. Still keyless, Ron is assigned to desk duty on the job. Frustrated, he soon discovers that Hilda Durn, elderly resident, has been stealing other town resident’s keys and going in and arranging their belongings at night, in order to keep the town safe. Officer Ron vows to keep her secret.

As the mystery of the ghost factory deepens, Armillaria Quaestio, the gigantic fungus that lives underneath the woods, makes a reappearance and engulfs the historic Lindholm house. While searching for the location of the childrens’ remains, Violet and Iris encounter Agent Oberman, who has been looking into evidence of temporal distortion in town, echoing Mr. Englebrecht’s notion of past and future colliding. Moments later, they receive another ghostly message, beseeching them to explore the ruins of Samuel Lindholm’s house for the missing compass. What new hidden dangers will Violet uncover next?

After locating the missing compass from Samuel Lindholm’s ruined house, Violet and Iris head deep into the woods where, with Holly Peterson and Officer Ron’s help, they discover a ghostly tree full of burned shoes and clothes, which marks the final resting place of the children who died in the Ames Rifle factory fire. Officer Ron alerts the police and medical examiner and Holly decides to hold an impromptu memorial service the following day. The floating factory soon disappears and, several days later, Holly begins night school for ghosts and disappeared persons, along with Gary Dublowski’s technical help.

Meanwhile, Officer Ron begins to follow town council candidate Owen Brandt after finding him knocking down his opponent’s signs. Eventually this leads to a pointed confrontation in which Brandt threatens Officer Ron’s job. While on a patrol, Officer Ron also discovers The Void has begun to make a loud hum, and although Mayor Zisk promises otherwise, this new shift seems to mark a decidedly dangerous escalation in The Void’s appearance.

On Halloween, Violet returns from a disappointing day at school to find that Jock Reynolds of the Historical Society has left a strange gift for her: a disappearing box, one of prankster Buck Walter’s final creations. Violet stares at the object for a while before putting one of her mother’s pens inside and closing the box. Moments later, Violet opens the box and finds a compact disc with her mother’s writing on it. What might this latest clue from beyond reveal about the nature of time and disappearances in town?

After following a crime report on the town’s website, Violet and Iris are horrified to find Professor Everard Bright, beloved cult theorist, dead by apparent bee sting at the Question Mark Motel. While Iris pretends to faint, Violet sneaks inside the room and spots a final clue to decode. As the town confronts this latest murder, Violet shows Officer Ron the deciphered message and Officer Ron reasons the hideout of the Order of the Arranger must be the Hall of Dazzling Glass at the nearby abandoned Question Park.

At the park, Violet and Officer Ron discover Glenn Warner of the Office of Vital Records and Art Compton, manager of Question Mark Foods, hiding within the mirrored attraction, with several maps and explosive materials. After handcuffing both suspects, Officer Ron travels deeper into the maze and finds town council candidate, Owen Brandt, who has been wounded and deeply frightened, muttering something about a ghost tiger, a possible reference to the park’s missing tiger, Sheba. All three suspects are booked for trespassing as the QM Police gathers additional evidence.

The entire town waits as the results of the election for town council are announced. Violet is pleased to learn Gerald Ames, assistant librarian, has won Tom Childs’ vacant seat, but expects something terrible to happen. Instead, returning home from a long day at school, she finally works up the nerve to listen to the CD from her mother and discovers the first track is David Bowie’s “Life on Mars,” which returns Violet’s sense of hope.

Meanwhile, Officer Ron attempts to support ex-convict Judah Towns, as he recognizes both feel trapped by their past mistakes.

As Violet and Iris feel a sense of normalcy returning to the town, they spot Mayor Elizabeth Zisk’s car at the Question Mark Motel. Once she departs, they watch Gerald Ames exit the same motel room, and dispose of a note. Reading between the lines, they learn the Mayor and Gerald Ames seem to have been meeting in secret for some time. What might this latest development mean for the future of the town?

On the way home from school, Violet discovers A. quaestio, the gigantic underground mushroom, has broken through the center of town and is engulfing the town square and destroying the Mayor’s beloved fountain. Later that day, while doing homework in her room, Violet notices a flash of purple light. Going outside to investigate the next day, she puts on a mask and discovers the fungus has released a strange wave of spores from the center of town and that most of the townspeople including Violet’s father, Iris, Bruno Ellis, Ms. Holly Peterson, Ms. Twombley, and baby Freddie, are now all unconscious.

Violet locates Officer Ron, who has been out of town looking into allegations surrounding the mysterious CM Waldorf. Together they find Mayor Zisk in tears at her ruined fountain. Violet hurries to the library and discovers a similar incident happened before in Question Mark in 1993 after a poisonous explosion at an illegal pyrite mine owned by Thompson Zisk. Violet heads alone to the mine and locates several crates of hazardous materials and then receives a message from Quentin Quinn, warning her that history is repeating itself and the answer may lie at the Cell-Con plant, the cell phone factory formerly owned by Thompson Zisk.

At the abandoned factory, Violet and Officer Ron find an old safe containing several documents that reveal a second incident occurred in 1998 after a chemical spill at the Cell-Con plant, leading to several dozen people becoming immobile. Decoding a private letter to Mayor Elizabeth Zisk, Violet also learns that Thompson Zisk claimed to have buried hazardous waste somewhere in town and may have also burned down his own factory in order to destroy evidence and sever ties with his failing business.

Following these clues to the town dump, Violet and Officer Ron make another unbelievable discovery that may explain strange symptoms currently affecting town members, but will this discovery come too late?

After locating the APEX shipping container full of hazardous waste, Violet and Officer Ron hurry to the Experimental Crop Station where Dr. Allison Andrews and her remaining team are able to quickly create an inoculation. Violet is overjoyed once her father regains consciousness and Officer Ron tends to his ex-wife, children, and Holly Peterson, who, in return kisses him in the school gym in front of the entire town.

Violet receives another startling message from Quentin Quinn, and inspired by a note in the town roundup, decides she will do everything she can to find the missing boy. Following his clue, she begins to search places in town where time seems to have stopped, beginning with the clock tower. Although she finds no sign of the missing boy, a strange interaction with newly-elected town council member Gerald Ames gives her pause.

With information gleaned from the public library, Violet attempts to find an old well, which has been said to appear and disappear, but again with no clue to Quentin’s whereabouts. Instead she finds Bruno Ellis sitting on a rock, overcome with grief for his decapitated cat, Ajax. Violet comforts him and invites Bruno and several other townspeople to her house for Thanksgiving, where Mayor Zisk makes a surprise appearance. At the end of the evening, Quentin Quinn’s mother, Gloria, comes bearing another message from the missing boy.

Meanwhile, Officer Ron comforts his son, Gary, who is struggling with the ongoing uncertainty in town, and offers his daughter’s ex-boyfriend, Parker, a place to stay. Getting a lead from Judah Towns about illegal happenings at the pyrite mine, Officer Ron must face his fear of being underground in order to dig deeper into the Circle of Concerned Families and Friends plot.

On Friday, Violet asks Bruno for help and the pair sneak into the abandoned Foreverland pet refrigeration building, where they make a startling discovery: three carefully frozen bodies, all belonging to the Applenight family. Moments later, Bruno notices a strange light coming from the lower level and Violet and Bruno continue their investigation, which may lead to some shocking truths about Bill Twombley’s disappearance and the nature of how time works in Question Mark.

Investigating Foreverland Pet Refrigeration for answers to the disappearance of Quentin Quinn, Violet and Bruno Ellis follow the strange light into the lower level and discover the silhouettes of three human beings etched into the concrete floor, all surrounding an ominous-looking power source. Bruno momentarily switches the machine on and, for a split second, Violet believes she sees Bill Twombley as time collides with itself once again.

On the way to alert the QMPD, Violet and Bruno are attacked by members of the Order of the Arranger moments later, demanding to know how to open The Void. Violet bravely fights the masked assailants off as Bruno once again comes to her aid.

With FBI Agent Adam Oberman’s assistance and the use of his recently-compiled time map, Violet searches the town for other places where time seems to stand still. Violet and Agent Oberman head to the Ames Tannery and find a bewildering scene: once-dead animals seem to come alive. Both Violet and Agent Oberman quickly retreat, finding no other clues leading to the whereabouts of Quentin Quinn.

Together they also search the ruined fairgrounds on the outskirts of town where 42 people were killed in a blizzard during the Winter Carnival in 2019. Violet notices that all of the blue spots on Agent Oberman’s map seem to correspond to a tragic event in town. As they stare over the fair’s wreckage, Violet receives another message from the missing boy.

Meanwhile, Officer Ron speaks with Judah Towns about his connection to the mysterious C M Waldorf and the Circle of Concerned Families and Friends and learns Waldorf is involved in a scheme to sell drugs in order to finance the acquisition of important religious relics. Traveling to nearby Marietta, Officer Ron attempts to follow the ghostly figure he spotted at the pyrite mine but is unable to trace his whereabouts. With Detective Barry McDonnell’s help, Officer Ron learns it is none other than Jules Friend, an out-of-work actor who once appeared on The Green Fog.

As Violet’s search to find Quentin Quinn grows closer to answers, what new secrets will be revealed?
