"My father was a warrior. He bade me fight..." Britain, 427 AD. Rome has abandoned the province, leaving it exposed to waves of barbarian invasions. To the west, savage pirates from Hibernia ravage the coastline. In the north, the crumbling defences of the Wall cannot contain marauding bands of Picts as they sweep down from the highlands. Worst of all are the Saxons, the dreaded sea-wolves. Under their chiefs, Hengist and Horsa, they wish to drive out the native Britons and claim the entire island for their own. Attacked from all sides, the Britons find a champion in the form of Ambrosius Aurelianus, the last of the Romans. A modest man, riddled with doubts and fears, Ambrosius reluctantly takes on the mantle of Dux Bellorum, Leader of Battles. Placed in command of Britain's only standing army, he fights to preserve the dwindling light of civilisation while the treacherous High King, Vortigern, plots his destruction. Set before the coming of Arthur, the first book of the Leader of Battles trilogy charts the rise and fall of post-Roman Britain's first great hero, and his desperate struggle to hold back the shadows threatening to engulf his country.
