Dirk Pitt, the director of the National Underwater and Marine Agency, is on the Black Sea, helping to locate a lost Ottoman shipwreck, when he responds to an urgent Mayday—“Under attack!”—from a nearby freighter. But when he and his colleague Al Giordino arrive, there is nobody there. Just dead bodies and a smell of sulfur in the air.

As Pitt and Giordino explore, a blast from the stern scuttles the ship swiftly, almost taking them with it. The more the two of them search for the secret of the death ship, the deeper they descend into an extraordinary series of discoveries. A desperate attempt in 1917 to preserve the wealth and power of the Romanov Empire.

A Cold War bomber lost with a deadly cargo. A brilliant developer of advanced drone technology on an unknown mission. Modern-day nuclear smugglers, determined Ukrainian rebels, a beautiful anti-terrorism agent from Europol—all will combine to present Pitt with the most dangerous challenge of his career.

And not only Pitt. His two children, marine engineer Dirk and oceanographer Summer, are exploring a mysterious shipwreck of their own, when they are catapulted into his orbit. The three of them are used to perilous situations—but this time, they may have found their match.


美國國家水下與海洋組織的主席德克‧皮特，在黑海協助尋找失蹤的鄂圖曼帝國沉船時，偵測到鄰近貨船發出的無線電緊急求救訊號——｢遭到攻擊！｣但皮特與同事艾爾‧佐丹奴趕到後，卻不見任何人，現場僅餘遺體與空氣中的硫磺味。

皮特和佐丹奴探查時，船尾突然爆炸，兩人差點同船身一起迅速沉沒，而兩人越是深入搜查船隻的秘密，越是身陷於一系列驚奇的發現，也就是關於1917年，羅曼諾夫王朝企圖孤注一擲保存王朝財富與政權。

一架冷戰時期的轟炸機和致命貨物一同失蹤，一位先進無人機技術的傑出開發者正執行秘密任務，現代核武的走私者、堅定的烏克蘭反抗軍、美麗的歐洲刑警組織反恐特工……上述種種交織成皮特職業生涯中最險峻的挑戰。

皮特的兩個孩子——海洋工程師小德克和海洋學家桑莫，也自行著手探查一艘神秘沉船，然而他們卻捲入到了父親的沉船搜查。已習慣身處險境的三人，這次卻可能遭遇到了對手。
