"One of the most suspenseful wilderness thrillers since
Deliverance." --Associated Press
Cody Hoyt, although a brilliant cop, is an alcoholic struggling with two months of sobriety when his friend Hank Winters turns up dead. At first it looks like suicide, but Cody knows Hank better than that. After years of bad behavior with his department, Cody is in no position to investigate a homicide. But he will stop at nothing to find out who murdered Hank.
When the murderer is linked to an outfitter leading a multi-day wilderness trip in Yellowstone National Park, Cody is desperate to get on the trail and stop the killer in his tracks. There's only one catch: his own son, Justin, is among the tourists. Now, in one of the most remote places on earth, Cody must enter a deadly cat-and-mouse game with a ruthless enemy who seems to know his every move.
