There are two sides to Captain Tom Skinner. One follows orders. One follows his gut. To keep the wild, untamed Arizona Territory safe, he's going with his gut.

Damnable news has reached Fort Verde. Outlaw Jessup Henry and his gang of thugs are raising hell north of Santa Fe, one homestead massacre after another. Now they're on the run in Arizona Territory evading the law. Cavalryman Tom Skinner's command: charge south with his patrol and wipe them out. But Skinner knows the land. Military decree be damned, he's deserting the wayward route--against orders--for the right one. There's more at risk than his career. In Jessup's path is the vulnerable ranch of his newfound love, Veronica, and her family.

After a race to deliverance, Skinner arrives too late. Veronika and her brothers are still alive but what his courageous gal's been through pushes Skinner over the edge. Now it's a breakneck gallop toward vengeance. Every outlaw on the Mongolian Rim is a target. Every bone-jarring mile is more treacherous than the last. This aims to be the bloodiest road a soldier's ever tread. For Skinner and his prey, the one who rides hardest will be the last one alive.
