Cady has another memory of summer fifteen. She gets into an argument with Granddad over the ivory goods he had gotten Tipper in China. She objects because ivory is illegal. She sees her grandfather as privileged, as someone "who didn't care who got hurt, so long as his wife had the cute statues she wanted to display in her summerhouses" (111). Cady urges Granddad to sell the ivory and give the money to charity. He gets angry.

Cady hangs out with the Liars at Cuddledown. Gat suggests they "act like friends and forget what happened" (114). But Cady wants to remember. She wants to hold Gat and never let go. She convinces herself to be normal for now and not make a fuss. She gives Gat some fudge and is joyful when he loves it.

Cady and Mirren make a trip to Edgartown. Cady experiences a memory of summer fifteen. Gat gave her a novel with the inscription: "For Cady with everything, everything, Gat" (116). Mirren suggests Cady did something wrong to Gat during summer fifteen. He has reason to be mad, she says.

The Liars gather on the roof of Cuddledown and talk about where they want their ashes placed when they die. They choose the little beach. They reveal their characters by saying who they would not want at their funerals. Johnny does not want "art types" while Mirren does not want "fake girls" (121). Cady realizes they are young forever on the island, no matter what changes come after.

Cady continues to spend time with the Liars. Johnny plays games, Mirren paints, and Gat reads. Cady feels a strong longing for Gat.

Cady tries to get Johnny to tell her about summer fifteen, but he refuses. He tells her Gat wants them all to act normal, like nothing happened. Johnny also tells her Gat is angry about how he behaved toward Raquel during summer fifteen: "He knew it wasn't right and he hated himself for it" (125).

Cady makes a gift of a book for Gat—Charmed Life, by Diana Wynne Jones. It is one of the stories her mother read her and Gat when they were both 8 years old. He is not in his bedroom, so she leaves it on his pillow.

Cady and Gat sit on the roof of Cuddledown. He asks if she has a boyfriend in Vermont. She says her boyfriend is Percocet, a drug, and he says she wants people to feel sorry for her. Gat reveals that Granddad paid for Cady’s trip to Europe the summer before. Gat tells her that her life has a million possibilities because of her wealth, but she says she wants to end her life. He gets angry with her. Then, he kisses her and she feels better. They stay on the roof "for a very long time. Forever" (130).
