Five friends. Four love stories. One devastating secret. Avery, Isabella, Odina, Lee, and Josie are young, wild, and inseparable. They've been best friends ever since they spent their first summer together at a surf camp on a small island off the coast of South Carolina. It was the best summer of their lives-until Josie suddenly disappeared without a trace. A decade passes before a new clue surfaces. Ten years later, Avery, now a successful but exhausted rockstar, returns to the island, hoping to move on from her bandmate Jake. But when she arrives, she discovers much more than just closure. The group's friendship has long since fractured, but as the truth of Josie's disappearance begins to reveal itself, Avery must enlist the help of her former friends to uncover the truth about their decade-old mystery. Her friends... and Jake. The man who knows her better-and has hurt her more-than anyone. Why is he finally fighting for her now, when everything else seems so lost?
