Juan Cabrillo and the crew of the Oregon find themselves exposed when a brilliant scientist blows their cover in this adventure in the #1 New York Times –bestselling series.   In 1902, the volcano Mt. Pelée erupts on the island of Martinique, wiping out an entire city of thirty thousand—and sinking a ship carrying a German scientist on the verge of an astonishing breakthrough. More than a century later, Juan Cabrillo will have to deal with that scientist’s legacy. During a covert operation, Cabrillo and the crew meticulously fake the sinking of the Oregon —but when an unknown adversary tracks them down despite their planning and attempts to assassinate them, Cabrillo and his team struggle to fight back against an enemy who seems to be able to anticipate their every move. They discover that a traitorous American weapons designer has completed the German scientist’s work, and now wields extraordinary power, sending the Oregon on a race against time to stop an attack that could lead to one man ruling over the largest empire the world has ever known. “ Piranha is a perfect beach read…the best entry in the series to date.” – Associated Press   “The action is supercharged.” – Kirkus Reviews   “Cussler scores a direct hit.

ONE Chesapeake Bay Nine months ago The X-47B prototype attack drone made a sweeping turn, only minutes away from the target eighty miles northwest of the Chesapeake Bay Bridge Tunnel. Frederick Weddell adjusted the frequency-hopping algorithm of the jamming transmission. His mission was to block the control signal coming in from the drone’s operator at Naval Base Ventura County in California and recode its onboard navigation system, causing the aircraft and its one thousand pounds of fuel to smash into a derelict barge. Even without the two smart bombs it was capable of carrying, the drone could cause a deadly terrorist attack on the U.S. Weddell relished the challenge. “We’re gonna do it,” he said to no one in particular, although there were two other men in the small room filled to the brim with electronic equipment and displays. The eighty-foot communications vessel anchored near the mouth of the Potomac was otherwise unoccupied except for its captain, who was topside on the bridge. Weddell adjusted his wire-frame glasses and looked up at the largest monitor to check the view from a camera on the deck. The drone was in its first turn after takeoff, a white wedge against the orange glow of dusk behind it. To accomplish their mission, jamming the control signal wasn’t enough. If the drone’s contact with its controller was lost, it would revert to autonomous mode and return to its base at Naval Air Station Patuxent River, the Maryland flight center that served as the test facility for most of the Navy’s aerial weapons systems. The key was to establish a new control authorization so that the coordinates for an alternative target designation could be loaded. In this case the unmanned aerial vehicle would be instructed to crash into the barge at five hundred miles per hour. This attack was the worst case scenario for the Pentagon. No one—not the drone designers nor the Joint Chiefs—thought that the onboard systems could be hacked. But ever since a top secret RQ-170 Sentinel reconnaissance drone crash-landed in Iran, top brass had demanded that the Air Force and Navy prove that their communications protocols were unbreakable. Apart from losing a drone that cost hundreds of millions of dollars to build, the crash had given Iran a free peek inside one of America’s most advanced pieces of technology. If the Iranians could bring it down, they might be able to wrest a drone’s control away from its operator. The military was pouring funds into a program to make su
