Deep Six by Clive Cussler
Dirk Pitt #7
 
A deadly tide of poison flows into ocean waters. A ghost ship drifts across the empty northern Pacific. A luxury Soviet liner blazes into a funeral pyre. The Presidential yacht cruises the Potomac night -- and the President disappears without a trace.

Dirk Pitt, the swashbuckling hero of Clive Cussler's smash bestsellers Sahara and Inca Gold, takes on a sinister Asian shipping empire in an intercontinental duel of nerves. In his most dangerous, fast-paced adventure, he fights to save the U.S. government -- and to seize one desperate moment of revenge!
