Dirk Pitt's 19th adventure, Treasure of Khan, is a second collaborative effort between father and son team, Clive and Dirk Cussler (after 2004's Black Wind). It offers a plot that is as credible as it is outrageous and the kind that entails the exotic aquatic detail that amazes, educates and entertains.
The treasure in question is that of Genghis and Kublai Khan, the great Mongolian conqueror and his grandson who founded the Yuan dynasty and ruled in what is today Mongolia and China. The villain in this story is a modern-day Mongol with dreams of restoring national power and pride. The heroes are Pitt, his sidekick Al Giordino and Pitt's son and daughter, Dirk Jr. and Summer, and they are all associated with Pitt's National Underwater and Marine Agency (NUMA).
Genghis Khan's grave site is one of the most sought after by archaeologists the world over. On Aug 4,1937 in Shang-Tu, China, Leigh Hunt discovered an ancient silk painting of a diagram of the hidden burial site of Genghis Khan. However, it does not remain in his possession for long.
Pitt and his NUMA colleagues are tracking the lake's currents when the earthquake hits.
Mongolia, a country with virtually no oil, then offers to supply China with a million barrels a day of high-quality crude oil. The Chinese Minister of Commerce wants to know who exactly is behind the deal and what they have to give in return. It turns out that the Avarga Oil Company is the interested party, and they demand strategic oil pipeline rights in exchange.
After rescuing a survey team from a freak wave on Russia's Lake Baikal, Pitt and Giordino later find out that their ship is being sabotaged and the survey team has vanished overnight. Pitt is forced to get to the bottom of a mystery with far-reaching consequences. Soon he's on his way to Mongolia where he and Giordino have several encounters with Borjin's army of trained horsemen and warriors. In typical Cussler fashion, Pitt manages to outwit his opponents, both physically and mentally.
And with the legacy of Khan and the lost treasures of Xanadu as the prize and the future security of the world at stake, there is no stopping Dirk Pitt from taking on the mission to solve one of the great mysteries confronting him and his team.
