Emma Sharp knows the rules of survival. From being raised by a doomsday-fearing father and hardened by the startup world, she has learned how to endure - especially in her marriage to Logan Grant, a charismatic tyrant who keeps her under tight control. To Emma, her marriage is a cage: it keeps you in, but it also keeps you safe. Until it doesn't.
When Emma forms an unexpected bond with Logan's former girlfriend, the two women form a plan to help Emma reclaim her life. Destination: the punishing final stretch of the Appalachian Trail.
After all, bad things happen in the woods all the time.
As the three venture deeper into Maine's backcountry, desire and dread curdle into something unpredictable, dark and deadly. Someone is lying. Someone is watching. And in the remote heart of the forest, someone is about to be lost . . . or found.
