Dirk Pitt is caught up in a dangerous and thrilling mystery on the murky waters of the Black Sea . . .

As Director of the National Underwater and Marine Agency, Dirk Pitt has always had a knack for finding rouble. This time, though, trouble has found him . . .

On a NUMA mission to the Black Sea to locate the wreck of a lost Ottoman Empire ship, Pitt and his friend Al Giordino respond to an urgent Mayday from a nearby freighter.

But by the time they reach the ship there's no one left alive - just dead bodies and the smell of sulphur in the air. When a massive blast from the stern suddenly scuttles the ship, Pitt and Giordino are lucky not to bed added to the death toll.

As they investigate the fate of the lost ship, they're plunged deep into an extraordinary mystery and make a series of discoveries.

And when connections emerge between a desperate attempt in 1917 to preserve the wealth and power of the Romanov empire, a Cold War bomber lost with a deadly cargo, modern-day nuclear smugglers and a brilliant engineer developing cutting-edge drone technology, Pitt is faced with the most dangerous challenge of his career. One that will threaten the lives of his family and friends.

Packed with breathtaking suspense, switchback plotting and remarkable imagination, Odessa Sea proves once again that, when it comes to adventure, Clive Cussler is in a league of his own.
