Blood Trail - C.J. Box (Joe Pickett Series, Book 8)

Game wardens have found a man dead at a mountain camp-strung up, gutted, and flayed as if he were the elk he'd been hunting. Is the murder the work of a deranged anti-hunting activist or of a lone psychopath with a personal vendetta? Wyoming game warden Joe Pickett is the man to track the murderer and stop him before someone declares open season on humans.
