A research vessel's crew is shipwrecked on a mysterious island with a deadly past in this terrifying thriller by a New York Times–bestselling author. Mark Hawkins, former park ranger and expert tracker, is on board a research vessel studying the Great Pacific Garbage Patch. But his work is interrupted when his ship is plagued by malfunctions and the crew is battered by a raging storm . . . The next morning, the beaten crew awakens to find themselves anchored in the protective cove of a tropical island—and no one knows how they got there. The ship has been sabotaged, two crewmen are dead, and a third is missing. Hawkins spots signs of the missing man on shore and leads a small team to bring him back. But they soon discover evidence of a brutal history left behind by the island's former occupants: Unit 731, Japan's ruthless World War II human experimentation program. As more of his colleagues start to disappear, Hawkins begins to realize the horrible truth: that Island 731 was never decommissioned and the person taking his crewmates may not be a person at all—not anymore . . . "Robinson puts his distinctive mark on Michael Crichton territory with this terrifying present-day riff on The Island of Dr. Moreau . . . One of the best Jurassic Park successors." —Publishers Weekly (starred review)
