On the lawless frontiers of the American West, there is one rule every outlaw should remember: Never cross a mountain man like Matt Jensen. Not if you want to keep breathing.

No gun. No horse. No water or food. And worse yet: No idea how he ended up in the middle of a desert with a bullet in his leg and a bump on his head. That's the sorry situation Matt Jensen wakes up to--dazed and confused--until he slowly pieces together what happened. The last thing he remembers: He agreed to help out a friend of Duff MacCallister's. A pretty lady and her husband at a horse ranch. He also recalls their cross-country trip through hell to deliver the horses safely to market. That's when the outlaws showed up. That's when the shooting began. That's when everything went dark . . .

But now Matt Jensen is alive and well and living for revenge. No time to lose. No holding back. And before it's all over, no trigger-happy horse thief will be left standing...
