After nightmares begin in the small town of Custer Falls, Montana, in 1992, it'll be thirty years before they end. Just outside of Custer Falls, something is sleeping. Life in the small town was never ideal, but it was safe, quiet, and predictable. After Wes Henson and his friends' field trip to Bloodtooth Caverns, all of that changes. All they did was stray off the path. They didn't expect to break their bones and discover an ancient relic. But once it's in Wes's hands, he's the one that has to put it back. Until he does, the town's nightmares are no longer harmless. The good side of your conscience may go quiet as the devil on your shoulder speaks up. Children fall into comas, while adults are torn to pieces in their sleep. If Wes and his friends want to survive, they'll have to conquer the waking world and the dreamscape. Because when this evil is awake, no one's dreams are safe.
