Wet Hot American Summer meets Emily Henry in the story of a young woman avoiding adulthood by working at summer camp, who is forced to confront the repercussions of her isolation when her old nemesis returns during her final summer.

Most 27-year-olds don’t live full-time at summer camp, but in the years since tragedy left Paige Schilsky alone in the world, Mirror Lake has become her home, from the climbing tower she can scale blindfolded to the renovated boathouse she’s decorated as most would their first apartment. When her boss tells her she’s overstayed her welcome, Paige resolves to make the most of her last season as camp director—until the arrival of an old colleague threatens to ruin her summer before it begins.

Handsome and cocky, Oliver Trevenen earned Paige’s ire from their first meeting, and nothing in the five years they worked together as counselors convinced her he was more than a loud mouth and pretty face. Now that he’s back—cute as ever and living in the spare room of her boathouse—Paige is determined to keep her distance, but it’s easier said than done in the bubble of summer camp. As they bring old camp traditions to a new generation and share late nights musing over the past, Paige discovers a sensitive person healing beneath Oliver’s irreverent facade—and reveals a side of her heart she’s long kept hidden.

But September is just around the corner, and with it the perils of adult life Paige has been avoiding. When camp ends, Paige must figure out whether a relationship nurtured by summer and nostalgia—and a life defined by it—can make it in the real world.
