843 AD

The city of Nantes Burns.

An unexpected betrayal forces Hasting to abandon his closest ally. With his heart turned black, he rekindles the savagery of his race. In sacking Nantes, his bravery and luck earn him a place in the skalds' songs. Word of his deeds reach his kin in the North, and more and more sea captains sail to Francia to join him, hoping his luck might help theirs.

Thor of Dublin, Hasting's old rival, will seek him out and bid him join his new alliance of Sea Kings. Together, they will launch the most ambitious raids their people have ever attempted. They will sail south to the land of the Moors to test their alliance's strength and, if successful, turn their sights to an even more daring prize: Paris.

The Norns make nothing easy. A secret affair will risk unraveling the alliance and bring the sea kings to the brink of civil war.
