In Dante, Arizona, in 1877, two outlaws from the Mortiss family demand a loaf of bread from Tom Worse, the town baker. What they get instead is a bullet to the head.

A century later, intelligence analyst Richard Worse is presented with two seemingly unrelated mysteries: a baffling plane crash near Dante, and a strange discovery in a cave across the ocean. As Worse investigates the desert crash, the Mortiss vendetta against his family reignites - and activity deep in the cave presents its own chilling danger.

Can Worse survive long enough to solve the case and eliminate the threat to his family line?
