Falcon MacCallister’s father was a legend in the West, but Falcon’s quest for justice has driven him onto the wild side of the law. Famed as a gunslinger, feared for his lethal speed and accuracy, Falcon decides to make it a fair fight when he comes up on a man being attacked by a bandit gang in the Dakota Territory.

The man is Teddy Roosevelt, the Rough Rider himself. Roosevelt knows a brave man when he sees one. And he calls on Falcon when a judge's daughter is taken by an outlaw trying to pry his brother free. With no trust in - or from - the law, Falcon has only one way to do this job: alone and ready to kill. But the outlaws know he's coming, the woman he's trying to rescue knows some tricks of her own, and winning a bloody battle in the Dakotas will take more than courage - it will take a man's will to live like a legend... or die like one.
