⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

Summary

After the rule change that freed residents from sleeping arrangements, the compound empties out socially. Lily sees Becca only occasionally and Tom mostly stays in the gray room. Their presence still bothers her, and she complains to Sam, who points out that they probably feel the same way about her and him.

One day, walking along the southern side of the grounds, Sam asks Lily what she is thinking. She recalls her mother and then a past contestant named Trish, a vivacious dancer who became withdrawn and was offered a phone call as a reward. Trish called her sister, briefly recovered, but left a week later. Lily wonders what it would take for her to get such a call, but she admits she has no former glory to return to.

Sam reminds her that they can now talk about personal lives. He says he would prefer to tell her about himself on the outside, because it is impossible to be completely real inside the compound. Lily pushes back, asking if he has been faking his feelings. He insists he hasn't, but that their communication has been constrained by the show. Lily says it will be easier to talk when the others are gone.

Then Sam abruptly suggests they leave that very day. Lily refuses, citing the prizes and opportunities. Sam calls the place fake and a wasteland. Lily argues that the outside is no better, that they are safe here. Sam asks her to ask him something personal. She asks about siblings. He reveals his two brothers died in the war, that his father pushed him to enlist, and that he eventually cut ties and moved, but was horribly lonely. He came to the compound because he hated his life. Lily explains she came because there is nothing else for her—she has no talent, no money, and this is her best chance. She admits she got a reward for talking to him early on.

Sam is devastated. He throws a stone through a window, then says he will fix it and leave. Lily goes for a swim and watches him repair the window. She thinks about how she loves him but cannot leave, and that she wants to win and be remembered.

Sam finishes and goes inside. Lily sees Andrew say goodbye to Sam, asking him to find Candice and tell her he thinks of her. Sam is noncommittal. Then Becca approaches Sam. She tells him she will leave soon, that she doesn't care about winning but just needs Tom to lose. She reveals the date is September 20th. Lily realizes the entire summer has passed. Becca says she has been tracking time with a notebook and lip liner.

Lily gives Sam a duck feather as a keepsake. He recounts the desert journey: they were dropped off individually, found each other by chance, Tom was bitten by a dog and killed it, Andrew and Tom fought, they voted Sam as leader, and Alexandre disappeared when he went to scout ahead and they voted to move on without him.

At the boundary, Sam doesn't kiss her goodbye. He tells her not to stay too long and leaves. Lily watches him go, then retreats to a back room where she stays alone for a while.

Themes, Symbols, or Motifs

Artificiality vs. reality: Sam argues that the compound prevents genuine connection, while Lily insists that feelings are real even in a constructed environment. The chapter questions whether any relationship formed under surveillance can be authentic.
Escape vs. staying: Sam chooses to leave, while Lily stays for prizes and fame. Their split embodies the central conflict between freedom and security, or between meaning and material gain.
Prizes and rewards: Lily's gold necklace and the phone call reward for Trish illustrate how the show uses material incentives to control behavior. Lily's admission that she got a reward for talking to Sam underscores the transactional nature of relationships in the compound.
Surveillance and performance: Lily is acutely aware of being watched, especially when she suppresses her emotions at Sam's departure. She recalls that girls who cry over boys lose sympathy, so she forces herself to appear cool.
Time and disorientation: Becca's revelation that it is September 20th shocks Lily, who has lost track of time. The chapter highlights how the compound distorts perception of time and reality.
Personal history and loss: Sam's story about his brothers and Lily's thoughts about her mother show how the past shapes their decisions. The desert journey also involves loss—Alexandre's disappearance—and the group's willingness to move on.
The boundary and crossing: The physical boundary represents a threshold between the artificial world of the compound and the uncertain outside. Sam crosses it, while Lily remains, symbolizing their divergent paths.

Why This Chapter Matters

This chapter is a turning point. Sam's departure removes Lily's closest ally and forces her to commit fully to the game. It also provides crucial backstory about the desert journey, explaining how the group arrived and revealing the violence and decisions that shaped them. The revelation of the date—September 20th—shows how long they have been trapped, and Becca's confession about wanting Tom to lose sets up future conflict. Lily's choice to stay, despite her love for Sam, defines her character and sets the stage for the final stretch of the competition.

Study Questions and Answers

Why does Lily refuse to leave with Sam, even though she loves him?

Lily refuses because she believes the compound offers her a chance at a better life. She has no talent, no money, and no prospects outside. The prizes and potential fame are worth more to her than a relationship that might not survive in the real world. She also fears that leaving would mean returning to a
