A game hunter is in a race against time to save his family from the most dangerous predator on earth?other people?in this high-stakes thriller in the vein of Jack Carr and Peter Heller.

Mason "Mace" Winters, with his acclaimed reputation as one of the best big game hunters in Colorado, lives for the thrill of the hunt. His lucrative career guiding the wealthy on intense hunts through the Colorado mountains is suddenly brought to a stop when an accident hangs an involuntary manslaughter conviction around his neck. Now he's relegated to a life of trash pickup in the very wilderness where his prowess as a tracker and killer was the stuff of legends.

At rock bottom, Mace descends into a haze of Tito's and sativa when two strangers seek him out. They wave enough cash under his nose to convince him to help them up into the mountains he knows so well on the opening day of Colorado's rifle season. An innocent enough request, and the perfect cover for the trip's true purpose: to assassinate an infamous warlord. All at once, Mace goes from unwitting to unwilling accomplice and it will take all his now dusty skills to outfox his patrons in their deadly game.
