Pacific Vortex!

Fully armed and with all hands on board, the nuclear submarine Starbuck sailed into the calm Pacific Ocean for sea trials ? and vanished. No wreckage, no signals, no survivors: nothing ... until ace maritime troubleshooter Dirk Pitt finds a single, chilling clue in the shark-torn surf off Hawaii -? the log of the Starbuck. A crazed journal of madness and death is all that remains. And the Captain's final, scrawled, fear-crazed note locates the Starbuck's grave hundreds of miles from her last known position! The search for the Starbuck plunges Dirk Pitt into his most shattering assignment to date ? a whirlpool of deep-sea mystery and terror ?- the Pacific Vortex!
