Fox is a character on an irregular TV show called "The Library." Jeremy Mars is a fifteen-year old boy who loves "The Library."

In one episode of the show, Jeremy sits on his roof in Vermont.

He is with his friend Elizabeth. They talk about constellations and their other friends. Jeremy thinks about kissing Elizabeth.

Jeremy’s mother is a librarian, and his father, Gordon, is a horror author. His parents have not spoken to each other in a week.

A woman named Cleo Baldrick dies and leaves Jeremy and his mother a telephone booth outside Las Vegas and a wedding chapel. Cleo is his mother’s great-aunt. Jeremy spends most of his time watching The Library, alone, with his parents, or with his friends. Everyone is obsessed with it. Elizabeth calls Jeremy and tells him that an episode is on. The show runs irregularly at odd times and on obscure networks. Jeremy wonders about the characters in Television shows and what shows those people watch.

Jeremy runs to Elizabeth’s house to watch the episode. His other friend, Talis greets him at the door. Talis is a mystery to Jeremy.

Fox died in the new episode. Prince Wig killed her.

In previous episodes of the show, pirate magicians say they will sell a cure to Prince Wig for Faithful Margaret’s hair which is always catching on fire. It is a trap. Fox had to save Prince Wig.

The cast swapped characters, except for Prince Wig and Faithful Margaret who are the main characters. They are always played by the same people.

They continue watching the show and talking about Jeremy’s inheritance. Jeremy goes upstairs to take a shower because he doesn’t want to see the episode again.

Jeremy, Karl, and Elizabeth have known each other since the first day of kindergarten. Their other two friends, Talis, and Amy are a year younger. Only Jeremy and Karl have always been friends.

Watching The Library brought them together. They think of what it would be like to always be inseparable like this—as if they are in a tv show.

When Jeremy comes back downstairs they are still discussing the show. Talis tells Jeremy that she had a dream about him and Fox. Fox told Talis to give Jeremy her phone number. Talis forgot the number when she woke up.

Karl and Jeremy walk home together later. Karl asks Jeremy what is up with him and Talis. Karl likes Talis. Karl tells Jeremy that Elizabeth likes him. They talk about The Library and whether Fox is really dead.

The Library is an obscure show and it has no credits. No one has ever taken credit for it.

Jeremy goes home and his dad, Gordon, is making a casserole. Gordon is a recreational shoplifter. He has a contract at the bookstore where he will autograph as many books as they ask if he can shoplift without consequence. His wife always goes to the store and pays for the books later.

Jeremy tries to talk to his dad. The conversation does not go anywhere. Jeremy goes to talk to his mom in the garage. She tells him that his father wrote him as a character in a story and gave him a brain tumor. Jeremy dies in the story. Because of this, she and Jeremy are going to go on a road trip to Las Vegas to sort out her great-aunt’s affairs.

Jeremy talks to his dad about the story. Gordon apologizes and expresses that he was going to save Jeremy in the story, but he kept getting sicker and sicker. He won’t let Jeremy read the story. Later, in his room, Jeremy calls a phone number that is written on a pad of paper on his desk. Someone breathes into the phone and then hangs up.

Jeremy has a dream about Fox. In his dream, he is sitting on a couch with Fox seated on either side of him. One Fox is played by Talis; the other is played by Elizabeth. They talk about being dead. Then they realize they are on TV. One Fox tells Jeremy that he has to keep calling her when he is awake.

Gordon Mars fashioned their van with couches in the back for the road trip. It reminds Jeremy of something from The Library

Jeremy tells his friends that he is leaving for a while to go on a trip with his mom. He tells Elizabeth on the roof. Elizabeth kisses him. Elizabeth tells Jeremy that Talis likes him. Jeremy tells Elizabeth that she can kiss him again. Elizabeth says they should have a surprise party for him at his house before he goes because his house always feels like Halloween. They are going to dress up as characters from The Library, eat ice cream, and watch The Library.

Jeremy calls his telephone booth every night. He vents to the silence on the other end of the line.

For his party, Jeremy dresses up as a Forbidden Book. He shows his father before the party. His father tells him he has not gotten rid of the book because he feels it is bad luck. Jeremy asks his dad not to shoplift while they are gone.

At the party, both Talis and Elizabeth arrive as Fox. Although, Talis arrives as dead Fox. Karl is Ptolemy Krill. Amy is Faithful Margaret. They watch The Library and have milkshakes. No one knows about Jeremy’s father’s book except Elizabeth. Everyone believes Jeremy is going on a fun trip with his mother and will be back by the end of the summer.

They talk about the library and wonder who the actors and writers are. They wonder where it comes from and if it is based on something true. Everyone goes to bed early except for Talis and Jeremy. Jeremy shows Talis the van. Jeremy tells her about his dream. Jeremy tells her that he has called his phone a few times and believes he is talking to Fox. Talis tells Jeremy that Fox isn’t real and that The Library is a tv show. They kiss and Jeremy pictures Elizabeth in his head.

At four AM everyone but Jeremy is asleep. He calls his phone booth. Someone who he believes to be Fox answers. She tells him that he needs to steal books from a library in Iowa and leave them in the phone booth outside of Las Vegas to save her. Jeremy agrees to do it.

The next day everyone says goodbye. Jeremy asks his dad how he shoplifts. Jeremy’s mom agrees to make a stop in Iowa. They go on the trip and make the stop. Jeremy steals the books in secret.

There is an episode of The Library which describes Jeremy’s road trip and his mission to save Fox whom he is convinced is not dead.

They make it to Las Vegas. Jeremy drops off his books in the phone booth. They arrive at the wedding chapel. There is a phone call waiting for Jeremy. A person dressed as a vampire gives him the phone. It is his friends from home. They tell him there is a new episode of The Library on and they ought to watch it together. He waits as the vampire is already flipping through the TV channels. Jeremy’s mother comes into the room with Miss Thing. Miss Thing also works at the chapel and agreed to help carry things inside. Miss Thing is holding a very expensive painting that Gordon Mars gave to his wife a long time ago. Jeremy sits down by the vampire and waits until they find the right channel so they can all find out if he saved Fox, if Fox is alive, or if Fox is dead.
