Dr. Kay Scarpetta is called to a very strange crime scene: in a spooky abandoned amusement park, a body with curiously red skin has been found in the center of a crop circle of petals. Horrified, she discovers that the victim is none other than a man she once loved, Sal Giordano. For Kay's niece, Lucy, the geometric shape leaves no doubt: the astrophysicist was thrown into the void from the top of an unidentified flying object. The authorities, meanwhile, question the scientist's loyalty to his nation and the debate rages. But when the autopsy reveals a clue that her former lover seems to have intentionally left for her, the head of the forensic institute sees an explanation that is both simpler, and far more terrifying...
