Fearless adventurer Dirk Pitt must unravel a historical mystery of epic importance in the latest novel in the beloved New York Times bestselling series created by the “grand master of adventure” Clive Cussler.

In 1959 Tibet, a Buddhist artifact of immense importance was seemingly lost to history in the turmoil of the Communist takeover. But when National Underwater and Marine Agency Director Dirk Pitt discovers a forgotten plane crash in the Philippine Sea over 60 years later, new clues emerge to its hidden existence.
 
But Pitt and his compatriot Al Giordino have larger worries when they are ordered to recover a failed hypersonic missile from Luzon Strait. Only someone else is after it, too…a rogue Chinese military team that makes their own earthshattering discovery, hijacking a ship capable of stirring the waters of the deep into a veritable Devil’s Sea.
 
From the cold dark depths of the Pacific Ocean to the dizzying heights of the Himalaya Mountains, only Dirk Pitt and his children, Summer and Dirk Jr., can unravel the mysteries that will preserve a religion, save a nation…and save the world from war.
