Eight years ago, Grace Simmons took a job as a counselor at the elitist Camp Willows to escape her lackluster life. She never anticipated meeting someone like Jocelyn Baker, heiress, mean girl, and Grace’s co-counselor. Grace is simultaneously fascinated and disturbed by Jocelyn. However, when Jocelyn betrays Grace to save her own skin, their friendship unravels. Grace wants revenge . . . Unfortunately, so does the man in black. Now, Jocelyn’s back in Cold Waters, suffering from delusions about the man who nearly killed her that summer, and Grace, burdened by guilt, visits her out of obligation. Jocelyn’s trauma is her fault, after all. At least, partially. But when Grace starts seeing the man in black, too, she realizes Jocelyn’s not crazy. The man in black is real. He’s here . . . And he’s stalking them both. Even as she’s forced to question her own sanity, Grace knows her survival depends on saving Jocelyn too. And that means telling Jocelyn the whole truth about that summer night, no matter the cost.
