The murder of two Environmental Protection Agency agents brings chaos to Wyoming Fish and Game Warden Joe Pickett's county in his latest thrilling case (after Force of Nature, 2012). Butch Roberson, a contractor who recently had a run-in with the EPA, is the prime suspect in the killings. Despite Butch's sudden disappearance, Joe, who has known him for a long time, has a hard time believing his friend has gone rogue. But the EPA--along with a band of vigilantes--think otherwise, and are determined to track Butch down. Can Joe find him first? An explosive thriller.
