USA Today -bestselling author David Poyer writes gripping undersea thrillers in the tradition of Clive Cussler and John D. MacDonald. On a moonless night in March, 1945, a Coast Guard destroyer sank a German U-Boat fifty miles off Hatteras Island, the Graveyard of the Atlantic. Now, a half-century later, the mummified corpses of three of its crewmen, wrapped in a decaying rubber raft, come to light during the excavation for a new shopping development. Their reappearance unleashes a tide of powerful forces . . . neo-Nazis with a ruthless plan to corner the South American drug market, an Isreali intelligence operative, and a shadowy, wealthy “historian” with his own, even more dangerous plan.

When Hatteras native, salvage diver, and ex-con Lyle “Tiller” Galloway III starts digging into the discovery, he’s forced by an island family cheated of their beachfront land to take on a dangerous silent partner. Together, he and Shadrach Aydlett will track down what actually happened in the Carolina sand hills so long before, and what everyone’s really after . . . tons of long-lost Nazi gold. And finally, face down a ruthless killer in a gut-wrenching battle that climaxes hundreds of feet beneath the surface.

Taut with vividly-told diving scenes, and delving deep into the rich lore and oral traditions of the Outer Banks, HATTERAS BLUE’s rare original hardcover edition sells for over a hundred dollars. This new ebook edition has been revised and updated by the author to make it even more fast-paced, exciting, and authentic.

Caught in the cross fire of a crazed underboss, hostile islanders, and a corrupt Bahamian government, Tiller and his Hatteras Island sidekick Shad Aydlett take on a nightmare of double crosses, as a scenario more sinister than he ever imagined begins to unfold.

Welcome to the most dangerous sport on earth: where cave divers step into murky Florida ponds and end up hundreds of feet below the ground, threading through the narrow passages of Swiss-cheese-like rock formations, heading down tunnels that may open into caverns of breathtaking beauty, or else suddenly collapse in rockfalls that crush out their air and their lives.

Open-water diver and ex-con Tiller Galloway has come to this watery underworld to find out why an old friend died young – and take one last shot at being a father, a lover, and a friend. But with a woman opening up her heart, and a deadly conspiracy closing in around him, Galloway must navigate between lies told aboveground and truths hidden in the depths . . . where a violent battle is about to explode.
