Fearless adventurer Dirk Pitt returns in an explosive new instalment of the No. 1 Sunday Times bestselling series created by the "grand master of adventure" Clive Cussler.
France, May 1940. As the German army blitzes Europe, a curator must take a mysterious cargo out of the country. When his intended ship sinks, his cargo's uncertain fate rests on a decrepit steamer, sailing under German fire.
Decades later, a diving expedition leads Dirk Pitt to a shipwreck's cache of uncut diamonds. No sooner than discovered, the diamonds are stolen - all while vital water treatment facilities around the globe are being targeted, placing humanity in grave peril.
Only Dirk Pitt can locate the treasure that will preserve the soul of a nation... and save the world from catastrophe.
