The year is 885 and England is at peace, divided between the Danish kingdom to the North and the Saxon kingdom of Wessex in the south. Uhtred, the dispossessed son of a Northumbrian lord, warrior by instinct, Viking by nature, appears to have settled down. He has land, a wife, two children and a duty given to him by Alfred to hold the frontier on the Thames. But trouble stirs, a dead man has risen and new Vikings have arrived to occupy London. Their dream is to conquer Wessex, and to do it they need Uhtred's help.
