Genghis Khan is the leader of a nation united from the tribes and victor in the long war against the Chin, Mongolia’s ancient foe.  Now there is trouble from another direction.  His embassies to the west are rebuffed and his ambassadors murdered. The nation must embark on their greatest journey, through present-day Iran and Iraq, to the edges of India.  They face enemies as powerful and ancient as any they have known and the Khan has chosen a path that will lead to victory – or utter destruction. Genghis has proved himself as a warrior and a leader, and now he must face the challenges of civilisation, what it will mean for his people and for those who come after him.
