On the way to hurricane-ravaged Isle of Palms, a barrier island off the South Carolina coast, Tempe receives a call from the Charleston coroner. The storm has tossed ashore a medical waste container. Inside are two decomposed bodies wrapped in plastic sheeting and bound with electrical wire. Tempe recognizes many of the details as identical to those of an unsolved case she handled in Quebec years earlier. With a growing sense of foreboding, she travels to Montreal to gather evidence. Meanwhile, health authorities in South Carolina become increasingly alarmed as a human flesh-eating contagion spreads. Someone is protecting a dark secret --- and willing to do anything to keep it hidden.
