For Vietnam veteran turned wildlife ranger Nick Drake, the war at home proves just as deadly.

Harney County, Oregon, 1968: Nick Drake has a chest full of medals and enough demons to fill a duffle bag. He's been trained to kill, but never retrained to rejoin society. Drake flees to the lonesome high desert in search of redemption and takes a job patrolling wildlife refuges where the only conflicts are keeping out stray cows and ticketing poachers. But then he stumbles across a girl's body ritually placed in a gully. Her murder is only the beginning, and Drake must face humanity's heart of darkness once again if he's to stop a killer from turning even more gullies into graves.
