⚠️ 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

The chapter opens with Skink confronting Lizzy in the campground office. He has taken her gun, the three-ring binder that holds The Book of Monsters, and the doll made from Lauren’s clothes and hair. His voice cracks as he tries to sound authoritative, but his red, bloodshot eyes betray exhaustion and fear. He orders Lizzy to sit, and she notices the gun on the desk—still loaded, she warns him. Skink admits he searched her van and took the items, convinced she is connected to Lauren’s disappearance. He also confesses to draining the gas from her van so she couldn’t flee.

Lizzy remains calm, explaining that she came to the island specifically to find Lauren, believing Lauren was taken rather than having run away. Skink reveals he has read the book and deduced that the monster described within is not Rattling Jane, but Lizzy’s own sister. Lizzy freezes at this revelation—the truth she has been carrying for years is finally spoken aloud. She confirms it, adding that her sister must have Lauren.

Skink is skeptical but clearly wants to help. Lizzy argues that calling his father would ruin any chance of finding Lauren, because the monster is leading her on purpose. She insists she needs to be the one to find her sister, and that other girls have gone missing too. Skink reluctantly agrees to help, but warns he will call his dad if he suspects any deception. He then tells Lizzy that her sister has added a new note at the end of the book—a note that he believes reveals where they have gone.

Character Development

Lizzy is pushed to her limit in this chapter. She has been carrying the secret of her sister’s identity for years, and now a teenage boy has uncovered it from the book alone. Her initial calmness is a mask; inside she is frozen, her body turning to ice. Yet she quickly pivots to persuasion, appealing to Skink’s desire to help Lauren. She admits she hates to involve him, but recognizes he is already too deep. Her plea is both manipulative and sincere—she genuinely believes she must be the one to find her sister, and she needs Skink’s cooperation to avoid police interference.

Skink evolves from a suspicious, defensive boy into a reluctant ally. He has clearly been losing sleep over Lauren’s disappearance, and his red eyes suggest he has been crying or awake for hours. His decision to read the book and piece together the sister’s identity shows intelligence and determination. He is cautious, holding his phone as a weapon, but ultimately chooses to trust Lizzy—at least for now. His warning that he will call his dad if anything seems off shows he is not fully convinced, but he is willing to take a risk for Lauren’s sake.

Study Questions and Answers

1. How does Skink’s deduction about the monster’s identity change the dynamic between him and Lizzy?

Skink’s deduction shifts the power balance. He has evidence and leverage, but Lizzy’s confession makes her vulnerable. Instead of turning her in, he chooses to help, creating a fragile alliance based on mutual need. His warning that he will call his dad if anything seems off keeps the power in his hands, but his willingness to listen shows he trusts Lizzy enough to give her a chance.

2. Why does Lizzy insist that calling Skink’s father would ruin their chances of finding Lauren?

Lizzy believes her sister is leading her on purpose, using Lauren as bait in a game. If the police become involved, the sister might panic or disappear, and Lizzy would lose her only chance to confront her. She argues that she needs to be the one to find her sister, because the sister’s actions are directed at her specifically. This insistence reflects her deep sense of responsibility and her belief that only she can end the cycle.

3. What does the note at the end of the book signify for the plot?

The note is a direct message from the sister to Lizzy, and Skink believes it indicates where they have gone. It transforms the book from a childhood artifact into a live communication tool. The note suggests the sister is aware of Lizzy’s pursuit and is actively guiding her, reinforcing the theme of manipulation and the idea that the sister is in control. It sets up the next chapter, where Lizzy and Skink will likely follow the clue.
