When law enforcement, the courts, and the prison system fail, there is a fourth and final option. #1 New York Times bestselling author Jack Carr launches a new thriller series.

Disillusioned by the government and institutions he dedicated his life to serving, former Navy SEAL and CIA ground branch operative Chris Walker is about to end his life when he receives a call that saves it. The wife of a teammate he lost in Afghanistan has now lost her son to the opioid crisis and needs Walker's help. Thrust into a conspiracy that goes deeper than he ever imagined, Walker must go up against the system and the very Constitution he once swore an oath to support and defend in order to find justice for his friend's widow.

With ambitious FBI agent Jarrett Stanton on his tail, Walker--accompanied by his loyal Belgian Malinois and using his off-the-grid VW pop-up camper filled with a hidden cache of weapons--takes the law into his own hands, exposing corruption and issuing a long-forgotten brand of lethal outlaw justice.

In the tradition of the great "stranger comes to town" Westerns of the past comes a modern interpretation of the mysterious vigilante gunslinger legend from "the hottest author on the thriller scene today" (The Real Book Spy). Get ready for a new kind of hero. Justice is coming.
