When seventeen-year-old Eleanor Willis arrives at Camp Sunshine, a camp secretly for LGBTQ+ girls, her mom's beat-up old car can barely make it up the hill. She decides to walk the rest of the way and admires a black Rolls Royce, before noticing the pretty girl with the blue eyes in the back seat. She wonders if this could be the start of a summer romance until the girl scowls at her and promptly rolls up the window.

It's just Eleanor's luck that she's fallen for Yvette Fleur, a half-French, rich, anti-social girl who wants one thing only: to leave camp as soon as possible. With Yvette's dad constantly traveling for work and her mom passing away when she was little, she's learned not to get attached to anyone. Eleanor wants to show her otherwise.

But Eleanor has her hands full as leader of Team Indigo in the lake crossing competition and must organize her team to build the fastest floating vessel for the big race. Unfortunately, she's stuck with two competitive over-achievers, an aspiring fashion designer who is more focused on their uniforms than the watercraft, and Yvette, who disappears every chance she gets.

To win the race and to win Yvette's heart, Eleanor must bring the girls together to work as a team. Maybe then Yvette will learn that not everyone leaves, if she'll only let them into her heart.
