Leagues below the sparkling blue water of the Caribbean Sea lies the mysterious wreckage of the Grave Descend. Protected by a wall of coral reef and blood-thirsty sharks, the corpse of the sunken yacht has been deemed unrecoverable by every diver in the world. Until James McGregor is offered a shot at it.

For McGregor, a thirty-nine-year-old diver with a long history of unsavory salvage jobs, it's his last chance at a big payday. But the more he learns about the wreck, the more questions he uncovers -- because none of the survivors are telling the same story. How did the ship really sink? What was its cargo? And why is this whole project starting to feel like a suicide mission?

With a new introduction by Sherri Crichton

From the Publisher:
An Edgar Award finalist from the #1 New York Times-bestselling author of Jurassic Park: A diver enters dangerous waters to recover a sunken yacht.
The Grave Descend lies under more than sixty feet of clear blue Caribbean water, guarded by a coral reef and schools of hungry hammerhead sharks. Raising it would be a near-impossible task, but James McGregor is suited to the impossible. An expert diver, he makes his living exploring sunken ships. But there's something strange about the wreck of the Grave Descend.

How did she sink? Why do none of the survivors tell the same story? And what was the cargo inside her hull? To answer these questions, McGregor will have to contend with the deadliest sharks around -- both underwater and on land.
