Full Synopsis
Dieter Harmon stared in shock at the sight of the hiker's corpse, the head hanging only by a tangled ribbon of flesh. But what horrified him were claw marks on the victim's chest. Something has gone terribly wrong with the government's plan to return wolves to Yellowstone.

As Dieter seeks answers, he is drawn into an escalating battle with Jack Corey, the chief park ranger. This is Corey's dream project. Wolves have been missing from the primitive beauty of Yellowstone for decades—it is past time to bring them back. For Jack Corey, this bitter fight is personal. And to his advantage, he knows well that in the remote back country tragic "accidents" happen.

That is where Dieter Harmon sets out to track a gruesome hybrid wolf that shouldn't even exist. But he soon finds that two predators are stalking him. They are very different in nature, but equally deadly.
