The U.S.S. Thomas Jefferson is one of the most powerful warships in the world. A nuclear-powered Nimitz-class aircraft carrier, it is believed to be impregnable. But when the Thomas Jefferson suddenly disappears at sea, the Pentagon is stunned. There was no warning. No apparent attack. And no survivors. All signs point to a nuclear accident. But subsequent reports suggest that a rogue submarine, armed with nuclear warheads, may be on the loose. Where did it come from? How could it get within striking distance of the Thomas Jefferson? Worse yet, where is it now? The deadly chase begins.

It's one of the stealthiest, most dangerous underwater warships ever built.and it's about to set off World War III.

Silent at less than five knots and capable of a massive nuclear warhead punch, it's the 240-foot Russian Kilo Class submarine. Strapped for hard cash, the Russians have produced ten new Kilos for Beijing. The Chinese have already received three of the subs and now the last seven are ready to be delivered—a code-red situation the Pentagon must avert. Armed with a full strike force of Kilos, China can cripple American interests, shatter the balance of power, and successfully achieve the unthinkable in the Pacific Rim. But not if the newly appointed National Security Adviser, wily Texas admiral Arnold Morgan, can stop them—using the navy's deadliest covert forces.

In a breathtaking race against time, a team of Navy SEALs penetrates deep inside the remote waters of northern Russia on a daring mission of destruction. And in the icy darkness of the North Atlantic, a brave U.S. captain takes his 7,000-ton nuclear vessel on a hair-raising trip beneath the polar ice cap to head off a powerful Russian cordon determined to transport the Kilos at any cost. Horns locked in a tense game of geomilitary survival, each of the world' three most powerful nations knows that one mistake will mean all-out war.

The H.M.S. Unseen is one of the most efficient, lethal submarines ever built. But suddenly, on a training mission off the English coast, it vanishes, baffling military intelligence on both sides of the Atlantic, including National Security Adviser Admiral Arnold Morgan. A missing weapon is dangerous enough. But then the unthinkable begins to happen....Planes begin blowing up across the skies.

Searching for answers, Morgan is convinced that only one man can be behind all these devastating events: his archenemy, the world's most cunning--yet reportedly dead--terrorist spy. Determined to stop his old nemesis, Morgan must use all his wits to find a madman armed with a powerful sub hidden somewhere in a million square miles of ocean. What Morgan doesn't know, however, is that the fanatical terrorist has a plan of his own, one that will bring these two intense warriors face-to-face--and only one will come out alive in one of the most chilling spy stories of the year.

Armed with stolen U.S. military technology, the Chinese are producing a frightening new breed of weaponry,led by the ICBM submarine Xia III -- a vessel that just might be able to launch a nuclear warhead across the Pacific Ocean and take out an American West Coast city.

National Security Adviser Admiral Arnold Morgan can't let that happen, and he dispatches the most stealthy hunter-killer submarine in the U.S. fleet, the 9,000-ton ultrasecret Seawolf, deep into the dark, forbidden waters of the South China Sea. But then the unthinkable happens: Seawolf, collides with a Chinese destroyer and falls into enemy hands. A team of cunning Navy SEALs -- the biggest Special Forces assault group assembled since Vietnam -- is sent in to free the captive Seawolf, crew and bring them home. The American Eagle confronts the Chinese Dragon with the balance of world power on the line. Failure is not an option...
