Nowhere to Run — C.J. Box

It's Joe Pickett's last week as temporary game warden in the mountain town of Baggs, Wyoming, but his conscience won't let him leave without checking out the strange reports coming from the wilderness: camps looted, tents slashed, elk butchered. Not to mention the Olympic hopeful who'd been training in the region and then just...vanished. What awaits him is like something out of an old campfire tale, except this story is all too real -- and all too deadly. Joe thought he was saddling up for his last patrol. If only he'd known how true that might turn out to be.
