Summary

Chapter 13 opens with Petra seething. She moves through the guests with a fixed smile, her tablet pressed to her chest like a shield, muttering curses at Eton under her breath. She has just witnessed something deeply wrong: three staff members huddled together, one of them—a woman named Lisa—openly crying and shaking. When Petra approaches, the staff instantly straighten up, wipe their faces, and insist everything is fine. Lisa, her name tag visible, forces a terrible smile and claims she is fine, that a spider startled her. Petra does not believe them. She manages to get Lisa alone, but the woman keeps up the act, glassy-eyed and wet-faced, insisting she is eager to return to work.

Before Petra can press further, Eton returns to the stage and announces a treasure hunt. At least half a dozen guests immediately bolt into the dark forest. Petra is forced to abandon her interrogation of Lisa. She catches up to Eton behind the stage and confronts him, furious. They had agreed he would announce the treasure hunt the next morning at breakfast, when it would be light. Eton shrugs it off, claiming the guests needed a distraction after the maze accident and the sirens. Petra points out that the injured contestant is exactly why the hunt should have waited—the jungle is full of hazards, and the guests have no lights. Eton deflects, even trying to take her hand, but she pulls away. He admits he moved the announcement because it felt like the right moment, given the cannibal witch legend and the appearance of the figure in the trees. Petra sees through his act; she knows he planned this and deliberately hid it from her.

She calls a truce and takes charge. She will send out search parties and hang beacon lights along the trails to guide guests back. She storms off, putting her smile back on before any guests see her. Internally, she worries about the staff member Lisa and about the island itself. Prosperity Island was supposed to be a haven, but it feels like quicksand closing around her.

The scene shifts to Ruth. She is numb, wandering, and overhears a group discussing something called the Petition cult. She approaches, and a woman named Gilly invites her to sit. Gilly explains that Petition was a suicide cult run by a man called Barom. The cult built a commune in isolation, centered on Barom's daughter, who was believed to have prophetic dreams. A council of elders—Sam interjects that there were five—interpreted the dreams to mean they must die to save humanity. The commune held a feast and drank a nerve toxin they had made themselves. Instead of a peaceful death, the toxin caused agony; the members went wild, running into walls, clawing at themselves, and tearing at each other. Police arrived days later to find all four hundred members dead, except the child. Her name was sealed by the courts, and she is known only as the Petition Child. Sam mentions a leaked police video showing the bodies and the child crouched in the dark, available only on the dark web.

Ruth listens, making faint noises, but internally she is reeling. She silently corrects Sam: there were seven elders, not five. She knows the details of the deaths intimately—the running into walls, the clawing, the glass. Gilly then delivers the chilling punchline: this weekend is the twentieth anniversary of the massacre, to the day. The group speculates that Eton chose this weekend deliberately, especially since the island itself was the site of a different cult's death. They suspect Eton has something planned.

Character Development

Petra emerges as the competent, responsible counterweight to Eton's recklessness. She is observant—she notices the staff's lies and Lisa's distress—and she is practical, immediately pivoting to damage control with search parties and beacons. Her anger is controlled; she hides it behind a smile for the guests. She also shows a deeper vulnerability: the island is beginning to feel like quicksand, and she is losing her grip on the situation. Her line about needing people to tell her when there is a problem, rather than pretend, reveals her frustration with the culture of forced cheerfulness that Eton cultivates.

Ruth is the emotional core of this chapter. Her reaction to the Petition story is visceral. She knows details that the others do not—the correct number of elders, the specific horrors of the deaths—and she silently corrects them. This strongly implies that Ruth is the Petition Child, the sole survivor, now grown. Her numbness, her broken voice, and her internal knowledge all point to a traumatic personal connection. She is not just curious; she is reliving the event.

Gilly is curious and somewhat eager, leaning into the macabre details, but she also shows a protective instinct, cutting off Sam when the descriptions become too graphic. She is perceptive enough to notice Ruth's discomfort and offers her water. Sam is more clinical, treating the story as a true-crime case, but he also connects the dots about Eton's timing.

Eton is shown as manipulative and impulsive. He claims he moved the announcement on a whim, but Petra knows he planned it. He uses charm and deflection to avoid accountability, and he is willing to risk guest safety for a dramatic moment.

Themes, Symbols, or Motifs

Distraction as a coping mechanism: Eton explicitly uses the treasure hunt as a distraction from the maze accident and the sirens. Petra recognizes this tactic but argues it is dangerous. The chapter suggests that distraction can be a way to avoid facing deeper problems.
Hidden truths and deception: The staff lie to Petra about Lisa's distress. Eton lies about his intentions. The Petition cult's elders twisted the child's dreams to serve their own agenda. Deception is layered throughout.
Prophecy and manipulation: The cult's elders interpreted the child's dreams to justify mass suicide. This motif echoes the island's own legends and raises questions about how stories are used to control people.
Survivor guilt: Ruth's reaction to the Petition story is saturated with guilt and trauma. She survived while four hundred others died, and she carries that weight silently.
Anniversary timing: The twentieth anniversary of the massacre is a deliberate narrative device, suggesting that past horrors are resurfacing. The group suspects Eton chose the weekend intentionally, linking the island's history to the cult's.
Island as a dangerous haven: Petra reflects that Prosperity Island was supposed to be a haven but feels like quicksand. The island's beauty masks its hazards—pits, cliffs, hypothermia—and its dark history.
Pandora's box metaphor: Petra thinks it is too late to close that Pandora's box once the treasure hunt is announced. This symbolizes the irreversible consequences of Eton's actions.

Why This Chapter Matters

This chapter is a turning point in the novel. It provides the first major exposition about the Petition cult, which is clearly central to Ruth's backstory and likely to the plot's larger mystery. The revelation that the anniversary falls on this weekend, combined with the island's own cult history, strongly suggests that Eton has orchestrated events to coincide with a significant date. The chapter also deepens Petra's role as the practical, ethical counterweight to Eton, setting up a potential conflict between them. Ruth's silent recognition of the details—the seven elders, the specific deaths—strongly implies her identity as the Petition Child, which will likely drive her actions in the coming chapters. The chapter ends with the group's suspicion that Eton has something planned, raising the stakes and foreshadowing a climactic event.

Study Questions and Answers

1. Why does Petra react so strongly to Eton's early announcement of the treasure hunt?

Petra is angry because they had explicitly agreed to announce it the next morning at breakfast, when it would be light. She knows the jungle is full of hazards—pits, cliffs, hypothermia—and that guests without lights are at risk. She also suspects Eton deliberately moved the announcement to create a dramatic moment, and she is frustrated by his dishonesty. Her reaction shows her priority on guest safety over spectacle.

2. What details in Ruth's internal reaction suggest she has a personal connection to the Petition cult?

Ruth silently corrects Sam's claim that there were five elders, thinking that there were seven. She also mentally recites the gruesome specifics of the deaths—running into walls, clawing at eyes, using glass to remove tongues—details that the others do not mention. Her voice breaks, and she feels numb. These intimate, accurate details strongly imply she was present at the massacre, likely as the Petition Child herself.

3. How does the chapter use the concept of distraction to develop its themes?

Eton uses the treasure hunt as a distraction to move guests past the maze accident and the sirens. Petra recognizes this tactic but argues it is reckless. The chapter suggests that distraction can be a way to avoid confronting deeper problems—whether it is the staff hiding Lisa's distress, Eton hiding his plans, or the cult's elders using prophecy to distract from their own agenda. The motif of distraction ties together the personal and the historical layers of deception.
