When NUMA director Dirk Pitt discovers a forgotten plane crash in the Philippine Sea, he unearths clues pointing to an invaluable Buddhist artifact that has been lost for decades. But soon, he will learn that he's not the only one making earthshattering discoveries. During a mission to recover a failed hypersonic missile from Luzon Strait, Pitt finds himself racing against a rogue Chinese military team...who have hijacked a ship strong enough to stir the ocean into a veritable Devil's Sea.

From the cold depths of the Pacific to the dizzying heights of the Himalayas, only Pitt and his children can unravel the mysteries that will preserve a religion, save a nation...and save the world from war.
