From the author of the bestselling The Dangerous Book for Boys  He was born Temujin, the son of a khan, raised in a clan of hunters migrating across the rugged steppe. Temujin’s young life was shaped by a series of brutal acts: the betrayal of his father by a neighboring tribe and the abandonment of his entire family, cruelly left to die on the harsh plain. But Temujin endured—and from that moment on, he was driven by a singular fury: to survive in the face of death, to kill before being killed, and to conquer enemies who could come without warning from beyond the horizon. Through a series of courageous raids against the Tartars, Temujin’s legend grew. And so did the challenges he faced—from the machinations of a Chinese ambassador to the brutal abduction of his young wife, Borte.
