Temüjin, the second son of the khan of the Wolf tribe, is only eleven years old—but his father died, his family was driven out by the tribe, and it seemed they were doomed to die without food and shelter. Across the endless stretches of the Mongolian plains, the boy will have to grow up early, learning to resist both people and the elements. Watching his family take in strangers and grow stronger, Temüjin saw a mighty future in uniting warring tribes. He was destined to do it. He would become the true ruler of the sea of grass—Genghis Khan.
