Dirk Pitt Adventures

Dirk Pitt battles his most dangerous foe ever - with help from a very unexpected source. There is a black tide infesting the ocean off the shore of Nicaragua. Whilst trying to determine its origin, startling things begin to occur and the inhabitants of a floating resort find themselves directly in the path of a violent storm. Dirk and the NUMA crew rush to their rescue, but they discover that there is an all-too-human evil at work and the black tide is only a by-product of its plan. Soon its work will be complete - and the world will be a very different place....

In the waning days of World War II, the Japanese tried a last desperate measure - a different kind of kamikaze mission. This one was carried out by two submarines bound for the west coast of the United States, their cargo a revolutionary new strain of biological virus. Neither sub made it to the designated target.But that does not mean they were lost.Someone knows about the subs and what they carried, knows too where they might be, and has an extraordinary plan for the prize inside - a plan that could reshape the world as we know it.

Genghis Khan - the greatest conqueror of all time, who at his peak ruled an empire four times the size of Alexander the Great's, a vast expanse which stretched from the Pacific Ocean to the Caspian Sea.And now somebody wants it back.Dirk Pitt and the NUMA crew are about to come head to head with their most dangerous enemy ever. A mysterious Mongolian mogul harbors a dream of restoring the conquests of ancient Mongolia. He holds a dark secret about Genghis Khan, his grandson Kublai Khan and the treasures of Xanadu - treasures of gold and also much, much more.

NUMA director Dirk Pitt and his children, Dirk. Jr. and Summer, have reason to believe there's a connection here somewhere, but they also know they have very little time to find it before events escalate out of control. Their only real clue might just be a mysterious silvery mineral traced to a long-ago expedition to find the fabled Northwest Passage.
