From a young scholar to one of history's most powerful warriors, this novel tells the story of Kublai Khan - an extraordinary man who should be remembered alongside Julius Caesar, Alexander the Great and Napoleon Bonaparte as one of the greatest conquerors the world has ever known.

A succession of ruthless men have seized power in the wake of Genghis Khan’s death—all descendants of the great leader, but none with his indomitable character. One grandson, Guyuk, strains the loyalties of the tribes to the breaking point, and another, Mongke, brutally eliminates the opposition and dispatches his younger brothers Kublai and Hulegu to far-flung territories.

Kublai—refined and scholarly, always considered too thoughtful to take power—will devise new ways of warfare and conquest as he builds the dream city of Xanadu and pursues the ultimate prize: the ancient empire of Sung China. His gifts will serve him well when an epic civil war breaks out among brothers, the outcome of which will literally change the world.
