In the Vikingverse, the Norse rule the stars with restless fleets and an iron will. But when the thralls rebel, turning to the artifice of Norns to help them escape their bondage, the natural order is thrown into chaos. The J?tunn War has been fought across the Nine Homeworlds to contain the threat, a battle against the stuff of ancient nightmares, red in tooth and claw. Utgard is the rebellion's last redoubt, an indignity the Empire plans to cleanse with flame and fury.
