Dispatched on a trial run, NASA's SuperAegis satellite has been created as the foundation of an international antimissle defense system. But moments after dispatch, it vanishes. Rear Admiral Jake Grafton fears something worse than a grave malfunction--he suspects sabotage...

The USS America--the world's most technically advanced nuclear submarine--is launched on its maiden voyage. Then shortly after steaming out of harbor, the unthinkable happens. Pirated by terrorists, America disappears beneath the roiling waves of the Atlantic, its Tomahawk warheads aimed directly at the United States...

An ingeniously calculated war has been waged--but the rouge enemy is far more insidious than Jake Grafton ever imagined. His mission: ferret out the core group responsible, overtake the stealth sub, and destroy it. But times is running out, and the race is on for Grafton to blow the covert operation out of the water before an entire nation is brought to its knees.
