Back of Beyond by C.J. Box

This book is a premium first copy, similar to the original but not the original.

Cody Hoyt is a brilliant but troubled cop who struggles with alcoholism. When his mentor is found burned to death, he suspects foul play, especially when the clues point to a murderer with a history of eliminating people in a gruesome fashion. The case takes him deep into the Yellowstone wilderness, where he must navigate treacherous terrain and face his own demons while hunting a killer who may be closer than he thinks.
