In District Attorney Alexandra Cooper's line of work, the discovery of a corpse isn't unusual. Not even the corpse of a young woman who was bound, bludgeoned and tortured to death. It's the location which is unusual - an abandoned Ferry Terminal at the southern tip of Manhattan. The ferries from here only went to one destination, the now uninhabited Governors Island. Also known as Ghost Island.

The corpse is identified as that of a part-time prostitute with a side-line in kink and a high-end client list. A list to kill for and, clearly, to die for... but the list is missing, and so is another girl. Alex, along with Mike Chapman and Mercer Wallace, fear the killer will find more victims before they can identify him. And when another young woman disappears at an isolated site not far from Governor's Island, Alex has no hesitation in joining the desperate hunt for a singularly depraved murderer. A chase which catapults her into one of the most chilling encounters of her life.
