Dragon, by Clive Cussler

A Japanese cargo ship bound for the United States is instantly, thunderously vaporized by Japanese fanatics with a chilling plan to devastate and destroy the Western powers. While Washington bureaucrats scramble, a brutal industrialist commands his blackmail scheme from a secret island control center. But from the ocean depths, NUMA agent DIRK PITT® is igniting a daring counterattack. Battling death-dealing robots and a human-hunting descendant of samurai warriors, Pitt alone controls the West’s secret ace in the hole: a tidal wave of destruction waiting to be triggered on the ocean floor!
