Pacific Vortex! (Dirk Pitt® #1) - Clive Cussler

Fully armed and with all hands onboard, 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.

'Do not search for us, it can only end in vain....' 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!
