The #1 bestselling author Conn Iggulden, coauthor of the international sensation The Dangerous Book for Boys, delivers a masterful novel of the mighty Mongol conqueror—as Genghis Khan sets out to unify an entire continent under his rule. For centuries, Mongol tribes had warred with one another. But now, under Genghis Khan, they have united as one nation, setting their sights on a common enemy: the great, slumbering walled empire of the Chin. Genghis will lead his warriors across the Gobi Desert and into a realm his people had never seen before—with gleaming cities, soaring walls, and canals. Laying siege to one fortress after another, he will crush each enemy in a different way—until his army faces the ultimate test of all.

In the city of Yenking—modern-day Beijing—the Chin will make their final stand, setting a trap for the Mongol raiders, confident behind their towering walls. But Genghis will strike with breathtaking audacity, never ceasing until the Emperor himself is forced to kneel.
