Four months after his best friend, Dodge, disappeared near their families' camp in a boat accident, Nate is still haunted by nightmares. He'd been planning to make the treacherous trek to the remote campsite with a friend -- his first time in winter without his survival-savvy father. But when his friend gets grounded, Nate secretly decides to brave the trip solo in a journey that's half pilgrimage, half desperate hope he will find his missing friend when no one else could. What he doesn't expect to find is the door to the cabin flung open and the camp occupied by strangers: three men he's horrified to realize have escaped from a maximum-security prison. Snowed in by a blizzard and with no cell signal, Nate is confronted with troubling memories of Dodge and a stunning family secret, and realizes that his survival now depends on his wits as much as his wilderness skills. As things spiral out of control, Nate finds himself dealing with questions even bigger than who gets to leave the camp alive.
