A straight through of Genghis Kahn's life by the author of Charlemagne and the March of the Barbarians this shows the signs of Mr. Lamb's skill at setting a character in his times and bringing him to life with good choice of the colorful elements that marked his career. Through the long conquering life of Temujin, as he was first known, he is shown clearly in his changing roles. There is the boy who, when his father died, clung tenaciously to family honor and gradually managed to gather a few followers from his small tribe. Known already for bravery, he was sought by other chieftains for advice. Through small battles at first, his control widened until he had China almost through the emperor's own volition. In the mighty sweep that followed clear to the doors of Europe, there is the strong sense of his value as a welder of east and west.
