She wakes up in a locked room. The rules are clear. Obey—or stop breathing. Sierra Hart’s senior year ends on October 5th. Trapped inside a concrete bunker with no windows and no way out, she’s given a full sheet of instructions detailing exactly how to survive—and what will happen if she doesn’t. The stationary bike bolted to the floor isn’t for exercise. It’s the only thing keeping her alive. As Sierra fights to endure the impossible, her disappearance fractures the small town of Laketown. Rumors spread. Loyalties crack. Her ex insists he knows nothing. Her father’s past resurfaces. Even her mother has secrets. But the deeper the search goes, the more unsettling the truth becomes. Because in Laketown, captivity isn’t only physical. Sometimes it’s about control. And sometimes the people searching for you are the same ones you should fear. Captivity has rules. So does love.
