#1 New York Times bestselling author Kathy Reichs returns with her twenty-second high-stakes thriller featuring forensic anthropologist Temperance Brennan who, following a series of bizarre disappearances on the islands of Turks and Caicos, enters a sinister labyrinth in which a new technology may wreak worldwide havoc. Called in to examine what is left of a person thought to have been struck by lightning, Tempe traces an unusual tattoo to its source and is soon embroiled in a much larger case. Young men—tourists—have been disappearing on the islands of Turks and Caicos. Seven years earlier, the first victim was found in a strange location with his left hand hacked off; subsequently, two other visitors vanished without a trace. But, recently, tantalizing leads have emerged and only Tempe can unravel them. Maddeningly, the victims seem to have nothing in common—other than the odd places where their bodies turn up, and the fact that none seems likely to have been involved in criminal activity. Do these attacks have something to do with the islands' seething culture of gang violence? Tempe isn't so sure. Disturbingly, she discovers evidence that what's at stake may actually have global significance. It isn't long before the sound of a ticking clock grows menacingly loud. Then Tempe herself becomes a target.
