Kyle William Lees saw his father and brother murdered by Confederate marauders at the close of the Civil War. The gang tried to kill him, too, but he survived. Now he carries a tattered list with thirteen names, and he is scouring the West in search of vengeance, crossing off one name at a time. When his quest takes him to Shakespeare, New Mexico, Kyle finds more than he bargained for, including the infamous Tom Brennan, one of the fastest and deadliest gunfighters around.
