On the trail, anything can happen. After secrets and betrayal shatter his marriage, Josh Mallory seeks solace on the Pacific Crest Trail, in the mountains of Washington. On the trail, he's just another hiker. On the trail, he can outrun the memories.

When wild animals destroy his food, Josh detours through a small mountain town. Missing hiker posters hang in the windows, and residents won't look him in the eyes, let alone speak to him or help him.

Trapped on a mountain ridge beneath a full moon and desperate for help, Josh moves on, only to encounter a mysterious group who call themselves the Woodkin. Hoping for food, shelter, and rest until he can hike back home, he soon realizes that he may never leave the mountain alive.
