Summoned to an abandoned theme park to retrieve a body, Dr. Kay Scarpetta is devastated to learn that the victim is a man she once had an intense love affair with. The murder scene is bizarre, with a crop circle of petals around the body, and Giordano’s skin is strangely red. Scarpetta’s niece, Lucy, believes he was dropped from an unidentified flying craft. Scarpetta knows an autopsy can reveal the dead’s secrets, but she is shocked to find that her friend seems to have deliberately left her a clue. As the investigators are torn between suspicions of otherworldly forces, and of Giordano himself, Scarpetta detects an explanation closer to home that, in her mind, is far more evil.
