The Civil War may be over, but fighting rages on as the United States expands to the West. The Native Americans resist this expansion as best they can, often responding to the slaughter of their people with their own waves of violence. Amidst it all, there are cynical men who see only opportunity for profit, selling the guns that accelerate the bloodshed and preying on the vulnerable, be they Native or not. James Hickok, a former Union soldier turned bounty hunter, wants justice more than rewards. And he will not stop until the men who orphaned a young girl get what they have coming—whether at the end of a noose or the end of a gun barrel.
