Elizabeth ‘Liz’ Raleigh has lost everything: her job as a police detective, her partner, her fiancé, and her peace of mind. After a month of solitude at a cabin in the woods, she finally feels as though she’s ready to move on. But in one terrifying night, everything changes. Liz's partner, Brody, appears in the form of a ghost. He's one of millions that have returned to haunt their loved ones. Brody can't remember how he died and Liz is determined to keep the secret of it buried, for it means dredging up crushing memories. Along with him comes an unearthly forest purgatory that swallows up every sign of human civilization across the world. The woods are fraught with disturbing architecture and monstrous wolves hungry for human souls. Brody says he escaped from them and that the wolves are trying to drag him and others ghosts back. As winter closes in and chaos erupts across New England, Liz fights desolation, resurfacing guilt, and absolute terror as she tries to survive one of the most brutal winters she's ever seen.
