Purgatory

The last mountain man is on the run for from the law—and out for justice—in this action western by the New York Times bestselling author of Deadly Trail.
 
Legendary gunslinger Smoke Jensen passed many things on to his adopted son Matt, including his sharpshooting skills and his unforgiving sense of justice. That usually means trouble for anyone who crosses him. But after an unavoidable gunfight in Purgatory, Arizona, Matt’s the one in trouble—sentenced to hang at Yuma Prison.
 
When the train from Purgatory to Yuma is violently derailed, Matt is set free amidst the carnage—and suddenly has a choice to make. He can run for his life and live like an outlaw or take a chance with the determined U.S. Marshall charged with hunting him down. As both he and his pursuer tangle with a vicious band of outlaws, they find themselves caught on the same bloody trail. . one that leads straight back to Purgatory.
