Valhalla Rising is Clive Cussler's thrilling sixteenth Dirk Pitt adventure.

Sabotage, conspiracy and piracy in the air, and below the waves, finds Dirk Pitt plunged into his most dangerous adventure yet.

When the luxury cruise lined Emerald Dolphin - powered by a revolutionary new propulsion system - becomes a raging inferno and sinks mysteriously, it is lucky that NUMA special projects director Dirk Pitt is on hand to rescue the passengers and investigate the tragedy.

Sifting through the undersea wreckage for signs of foul play, Pitt is unaware of powerful, dark forces player their hand against him. Forced to fight for his life - and those of friends and colleagues - against evermore ruthless enemies from a shadowy organisation, Pitt finds himself caught between the secrets of the past and the intrigues of the future. A future that will hold the world to ransom...

Filled with breathtaking suspense and dazzling action, Valhalla Rising sees Clive Cussler at the height of his storytelling powers. Valhalla Rising is the sixteenth of Clive Cussler's bestselling Dirk Pitt novels - the series that also includes Atlantis Found and, his first novel, Mayday - in which our hero finds himself caught up in a web of shipwrecks and dark secrets.
