Chapter 27 Summary, Analysis, and Key Moments

⚠️ 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 two weeks before the novel's main events. The last senior party of the year takes place at Blaine's lake house on Pine Lake, with Reading Week beginning the following Monday.

Kassidy and Izzy ride to the party in the Logans' chauffeured Bentley. During the drive, Kassidy tells Izzy about a Truth or Dare game with Fergus at a previous party, where she was dared to lick Blaine's cat, Queenie. Izzy is horrified, but Kassidy laughs it off, saying she never turns down a dare. Kassidy squeezes Izzy's hand and insists she is never allowed to skip a party again. Izzy points out that this is the last one, since Blaine will be staying with his dad all summer. Kassidy's laughter dies, and she softly calls it the farewell-forever party.

Izzy immediately regrets reminding Kassidy about the end of high school. While Izzy is desperate to leave Marian and Harker, Kassidy is already nostalgic for a time that is not even over yet.

They arrive at Blaine's modern glass house, which stands out against the traditional New England style of the other lake houses. Dozens of Marian students are already inside, dancing and talking. Blaine greets them at the door, admires Kassidy's dress, and enforces his no-keys rule with two juniors who try to sneak past him. Kassidy pretends to drop keys into his palm, saying Miguel drove them.

Blaine turns to hug Izzy, but she sidesteps him. The idea of touching Blaine in front of Kassidy makes her want to gag. Kassidy frowns at the rejected hug, and Izzy knows she needs to leave before the situation becomes uncomfortable enough for Kassidy to say something. She does not want to have to tell another lie. She says she is going to grab a beer and hurries to the backyard, reasoning that after a few drinks Kassidy will forget about it—people ignore things they do not want to see.

In the backyard, students crowd around the pool and hot tub. Ellison stands at the pony keg, wearing white swim trunks and a tight black T-shirt. He mentions they have already made it through the first keg. Izzy grabs a red Solo cup.

Blaine's backyard is as big as a park, with a grassy hill sloping down to the lake and rope swings dangling from the trees. A zip line runs from the top of the hill across the water to a giant blow-up pool anchored in the lake bed. Riders who hold on land in the pool, where beer cans float like prizes.

Ellison removes his T-shirt in one easy motion, and Izzy flashes back to an encounter they had in the back of his SUV after one of Blaine's parties junior year. He asks if she is coming to watch. Izzy never zip-lines—not because she is scared, but because gliding over a cold lake never appealed to her. But tonight, her rage toward Blaine is powering a feeling of recklessness. The farther she can get from him, the better, and the center of the lake is as far as she can get without leaving the party.

Izzy pulls her sweater over her head to reveal a long-sleeved bathing suit underneath, chugs her beer until only foam remains, and announces she is no longer a watcher—tonight she swings.
