A new Dirk Pitt novel from the Grandmaster of Adventure fiction. Genghis Khan - the greatest conqueror of all time, who at his peak ruled an empire four times the size of Alexander the Greats, 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 ever enemy. A mysterious Mongolian mogul harbours 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, yes, but also much, much more. His relentless pursuit of them will cause devastation to millions . . . unless Dirk Pitt can somehow find a way to stop him. Packed with blazing action and daring exploits, comes a nerve-shredding thriller from the best in the business.
