Norway AD 785. Sigurd Haraldarson has proved himself a great warrior . . . and a dangerous enemy. And yet the oath-breaker King Gorm, who betrayed Sigurd's father, still lives. The sacred vow to avenge his family burns in Sigurd's veins, but he must be patient and bide his time as he knows that he and his band of warriors are not yet strong enough to confront the treacherous king. They need silver; they need more fighters to rally to the young Viking's banner; they need to win fame upon the battlefield. And so the fellowship venture to Sweden, to fight as mercenaries. And it is there - in the face of betrayal and bloodshed, on a journey that will take him all too close to the halls of Valhalla - that Sigurd's destiny will be forged... The Vikings return in this thrilling, thunderous sequel to Giles Kristian's bestselling God of Vengeance. Sigurd's adventures continue in Wing's of the Storm.
