New Orleans is awash with corpses after Hurricane Katrina unleashes its awesome power. In a city patrolled only by looters, all law and order gone, the survivors wait in trees or on rooftops for help that never comes. In a landscape transformed into a violent wasteland, Dave Robicheaux must investigate the shooting of two looters and find out why some very dangerous people are hunting a third. Is it because they unwittingly ransacked the house of a notorious mob boss? Or did a chance encounter with the father of a raped girl seal their fate? As Robicheaux starts to uncover a ruthless tale of greed, torture and murder, his own family comes under threat from a sinister psychopath, and the devastated city provides the perfect stage for a final confrontation between good and evil.
