Viking warriors Hrolf, Sigrid, and the Laxdale clan continue their war against the alien invaders, traipsing across medieval Europe. Frostbite picks up where the last Spider King volume ended, as the clan make their way through an ominous snowstorm and are attacked by swarms of biting, fighting, talking animals.

When a fleet of spaceships crashes into northern Europe in 956 AD, a group of unlikely Viking heroes are the last line of defense against a brutal intergalactic warlord. Equal parts science fiction and fantasy, The Spider King follows the adventures of Viking warriors as they defend their world against alien invaders armed with futuristic technology and impossible weapons.
