'I rode out beneath the soft moonlight, with a single intent, to kill a man.' In the Territories one man is more evil and terrible than all others. From murdering Chinese immigrant workers on the Transcontinental Railroad to slaughtering anyone who dares beat him at cards, Moose Schmidt kills and maims or no other reason than to enjoy the surge of control and power it gives him. Callum Johnson's father was killed by Moose Schmidt when Callum was a young boy. Now it is payback time. Teaming up with his father's old Cherokee scout and a beautiful Chinese girl, Callum ventures deep into Moose Schmidt's territory seeking justice and revenge. But Moose Schmidt has eyes and ears across the land. He knows Callum is coming and he is ready and waiting. And determined to have fun killing the young man.

Armed with just a six gun and the lessons his father taught him, can Callum and his companions succeed where even the greatest bounty hunters have failed?
