"Jeremy Robinson blends myth, science, and terminal-velocity action like no one else."-Scott Sigler, New York Times bestselling author of Nocturnal

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 onshore 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 preying on his crewmates may not be a person at all-not anymore...

"Robinson, a skilled blender of the thriller and horror genres, has another winner on his hands."-Booklist
