When a Gulfstream jet goes down in the Bahamas carrying a fortune in cash and ill-gotten diamonds, expat diving instructor Michael Gannon is the only person on the scene. Assuming himself the beneficiary of a drug deal gone bad, Gannon thinks he’s home free with the sudden windfall until he realizes he forgot to ask one simple question. Who were the six dead men on the plane? Gannon soon learns the answer to that fateful question as he is thrust into an increasingly complex and deadly game of cat and mouse with a group of the world’s most powerful and dangerous men who will stop at nothing to catch him. But as the walls close in, Gannon reveals a few secrets of his own. Before he retired to the islands, Gannon had another life, one with a lethal set of skills that he must now call back to the surface if he wants to make it out alive.
