Genghis Khan is the leader of a nation united from the tribes. He was victorious in the long war against the Chin, the Mongolians' ancient foe. Now trouble arises from another direction. His embassies to the west are rebuffed, 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, but the khan has chosen a path that will lead to victory or utter destruction.

Genghis has proved himself as a warrior and a leader. He must now face the challenges ofcivilisation, what it will mean for his people and those who come after him. His sons have become generals. He must choose between them before they destroy all he has built.

One can only hope that the phenomenal success of his co-authored The Dangerous Book for Boys does not take attention away from the prodigious storytelling skills of Conn Iggulden. As Bones of the Hills forcefully reminds us, Iggulden is the real deal when it comes to historical fiction on the grandest scale. And here, all of his characteristic skills are well to the fore.

A boy was abandoned in the wilderness by his tribe -- but he did not die. As those Iggulden admirers who have read Wolf of the Plains and Lords of the Bow will know, this luckless boy has grown into one of the most feared and powerful figures in history, Genghis Khan. He has persuaded the tribes that had been tearing each other to pieces to ignore their differences and unite under his leadership to battle their oldest enemies. Under his ruthless (and ferociously inspired) leadership, a mighty nation has been forged. But this is only the beginning of his struggles: Khan sends out emissaries, but they are tortured and killed. He attempts to open trade routes; his efforts are met with violent rebuff. Soon, the Mongolian army is stretched to the furthest corners of Khan's realm, and destruction looms.

This is epic storytelling on a nigh-operatic scale. Iggulden has long been the master of the broad brush stroke and conjures up the ancient world with great panache. Of course, the success of a book such as Bones of the Hills depends on the vivid characterisation of its larger-than-life central character, and of the many novels which have attempted to capture Genghis Khan, none have mastered the task as successfully as Conn Iggulden.
