Hurricane Katrina has transformed New Orleans into a violent wasteland. Criminals capitalise on the devastation as survivors wait for help that never comes.

David Robicheaux - his city in ruins -- is tasked with investigating the murder of a pair of looters: is it a simple case of 'stand-your-ground', or something altogether darker? The dead men's accomplice holds the key but he has disappeared to escape the people hunting him.

As Robicheaux uncovers a brutal catalogue of greed, torture and murder, his own family is threatened, and the ravaged city provides the perfect stage for a final confrontation between good and evil.
