David Flynn is a legend in the rugged Arizona Territory—a U.S. cavalry turned army scout and the only man alive who can bring in the fierce Apache renegade Soldado Viejo. Tracking an elusive Indian with a price on his head south of the border is dangerous business. And when a cunning outlaw and a murderous bounty hunter dog his path, Flynn gets on a bloody trail of treachery and slaughter in a lawless land where a man has to watch his back against friend and enemy alike. On the deadliest mission of his career, in a sultry desert hell where the hunter becomes the hunted, Flynn's struggle for justice has just turned into the battle of his lifetime.
