From the author of Spontaneous comes a '90s mixtape of a young adult novel that delivers a summer romance with an unearthly twist. Perfect for fans of The Gravity of Us. "Starmer's eerie love story is spooky, sad, and sweetly funny--a highly original '90s retro mixtape of a book that will have you wishing you could go night swimming with Sarah and Trevor, until chills go down your spine and you realize what a very, very bad idea that would be."--E. Lockhart, author of We Were Liars and Genuine Fraud One final swim of the summer. Let's make it last all night... Summer, 1994. Trevor can barely wrap his mind around the fact that he and his friends have graduated high school. And yet there's no rush to get to college. He's determined to live one night at a time. Riding shotgun from party to party, windows down, music up, his focus is entirely on his crush, the enigmatic girl in the driver's seat. Will things ever go anywhere with Sarah? Maybe? Because Sarah has proposed a mission: They're going to swim all the pools in town. Before long, they're sneaking into backyards every night, splashing, floating, and loving every minute of it. But it's still not enough for Trevor. He yearns for Sarah, despite her college boyfriend, despite her "not yet"s, despite the way she keeps pulling away the moment it starts to feel truly magical. Things finally change when they learn about a natural pool hidden deep in the woods. It seems like just another spot to check off their summer bucket list. But once they get there, they realize that this place has a curious hold on them, and something very strange is happening...
