Inside the world's most advanced submarine, Vulkan, a man holds a list of U.S. targets — each one will mean millions of casualties and a world thrown into nuclear chaos. Capt. Cooksey knows that his elusive prey can be brought down only one way-betrayal. Someone within the Russian hierarchy is about to give the Americans the one tool they need to stop the Vulkan.

Equipped with the latest in stealth design and technology, fully armed and virtually invisible to conventional military tracking devices. Sea Devil is the lethal new submarine in a deadly enemy fleet. Under the command of renegade Admiral Igor Starobin, this top secret weapon spearheads a Code One operation to penetrate and destroy the U.S. Navy base at Holy Loch, Scotland, the strategic core of NATO’S defense advantage. Pentagon special investigator Commander Brad Mackenzie knows that the next secret enemy strike will occur along the unprotected shores of Scotland. At the helm of the super attack sub USS Bowfin , Mackenzie is soon locked in combat with the Sea Devil, chasing shadow signals and sound signatures in a desperate battle that will decide the future of the free world!

America's most advanced defensive surveillance satellite is hurtling towards Earth, leaving the United States susceptible to a surprise attack from the Soviet Union.

Fifty years after World War II, a fugitive SS officer is intent on retrieving Nazi war gold from a sunken U-boat in the North Sea. But his plans are interrupted by the arrival of the USS Cheyenne on routine NATO patrol — and a Russian nuclear attack sub on its own desperate mission of destruction.

The ultimate biological weapon lies in the hands of a Ninja warrior with a mad dream of reestablishing Japan as the world's mightiest military superpower. Only an obsolete diesel-powered submarine manned by a crew of specially trained computer-oriented nuke submariners can stop him. In one daring gamble, the engineering marvel of another time will be up against the high-tech weaponry of the future to decide the fate of the world.

The Soviet Premier's airplane suddenly veers off course, far above the frozen Canadian wilderness — and shockingly close to a brand new, state-of — the-art NORAD radar installation. Is the Soviet action a simple error or a tactical slap in the face? A squadron of crack F-15 interceptors and a squad of Canadian Arctic rangers race to the region where the plane has disappeared. Simultaneously, the new Baffin Island radar station goes active, showing NATO's hand, but poised to fend off a global crisis with the highest stakes. The U.S. Naval Arctic Weapons lab provides support with an untested surface scanning fathometer mounted in the hull of the U.S.S. Defiance, skippered by Captain Matt Colter and monitored by the device's inventor, Dr. Laurie Lansing. The Soviets counter by rushing an awesome Akula class attack submarine in the hand of young Captain Sergei Markova to search for signs of the plane beneath the Canadian pack ice — that is, unless the NATO forces get there first. With all of the technological might of East and West homing in on the pressure point in the icebound Davis Straits, cracks appear in ice and men, and a showdown unfolds with terrible stakes — the fate of humanity itself.

On an isolated highway in the Crimea, as the President of the United States races toward a top secret nuclear summit, high-powered weaponry suddenly opens fire on the motorcade, brutally slaying America's Chief Executive and those assigned to protect him. Above a rushing whitewater river in the Missouri Ozarks, a jet-black Huey helicopter appears from nowhere to rain death upon the traveling party of the U.S. Vice President. Only the quick, decisive actions of Special Agent Vince Kellogg of the Secret Service saves the V.P. from sharing the grim fate of the Commander-in-Chief. Without warning, the greatest nation on Earth been rendered leaderless. Liberty and democracy have been places under siege by a well-armed and organized foe — an enemy operating not from outside America's borders, but from within her own sacrosanct halls of power. And now a small handful of patriots must do whatever it takes to prevent America's legacy of freedom from becoming a thing of the past — and stem the tide of treason, nuclear terror, and death originating from the remarkable airborne sentinel called…
