The fall of Rome was just the beginning. A new empire will rise . . .

AD 439: the Roman Empire is on the brink of collapse. With shocking speed a Vandal army has swept through the Roman provinces of Spain and north Africa, conquering Carthage and threatening Roman control of the Mediterranean. But a far greater threat lies to the east, a barbarian force born in the harsh steppelands of Asia, warriors of unparalleled savagery who will sweep all before them in their thirst for conquest - the army of Attila the Hun.

For a small group of Roman soldiers and a mysterious British monk, the only defence is to rise above the corruption and weakness of the Roman emperors and hark back to the glory days of the Roman army centuries before, to find strength in history. But then they devise a plan of astonishing audacity that will take them to the heart of darkness itself, to the stronghold of the most feared warrior-king the world has ever known. In the showdown to come, in the greatest battle the Romans have ever fought, victory will go to those who can hold high the most potent symbol of war ever wrought by man - the sacred sword of Attila.
