The guns come down the Colorado River, cases of army rifles that could mean life or death for the soldiers fighting the Indian Wars throughout the American West, and Dave Harmon is waiting for them. A grizzled, one-eyed freight captain, Harmon knows better than anyone how to drive cargo over the broad, merciless desert. The rifles could attract Apache, bandits, or worse, but none of that frightens him. The real trouble is one of the passengers: a major’s beautiful daughter he’s not sure he can trust. Soon Harmon is fighting off not only ruthless outlaws and Apache determined to defend their land, but backstabbing members of his own wagon train. In order to reach Fort Whipple with the guns and the girl, he’ll have to take on his enemies singlehandedly—and destroy them all.
