It is AD 367, and Roman Britain has fallen to the vast barbarian horde which has invaded from the north. The army of Rome - once the most effective fighting force in the world - has been broken, its spirit lost and its remaining troops shattered. Yet for all the darkness, there is hope. And it rests with one man. His name is Lucanus who they call the Wolf. He is a warrior, and he wears the ancient crown of the great war leader, Pendragon, and he wields a sword bestowed upon him by the druids. With a small band of trusted followers, Lucanus ventures south to Londinium where he hopes to bring together an army and make a defiant stand against the invader.

AD 367. In a frozen forest beyond Hadrian's Wall, six scouts of the Roman army are found murdered. For Lucanus, known as the Wolf and leader of elite unit called the Arcani, this chilling ritual killing is a sign of a greater threat.
But to the Wolf the far north is a foreign land, a place where daemons and witches and the old gods live on. Only when the child of a friend is snatched will he venture alone into this treacherous world - a territory ruled over by a barbarian horde - in order to bring the boy back home. What he finds there beyond the wall will echo down the years.
