Lords of the Bow (Conqueror Book 2)

One man would become a legend. Under his hand, hunters and shepherds have learned to be warriors. They have only their bows, their horses and an iron discipline born of cold, hunger and death. The tribes gather to swear an oath of loyalty to Genghis Khan. The boy has grown strong, but strength alone is not enough. He has to lead the warriors in battle against a vast and ancient enemy. If they cannot win, everything he has made will be torn down and consumed in fire.
