Hailing from the hostile ice world of Fenris, the Space Wolves are as fierce and proud as their name suggests. Considered by some to be wild and undisciplined, the Sons of Russ are loyal to a fault, and their instincts for war are never in doubt. Woe betide those they mark as their prey, for they too shall feel the fangs of the wolf around their throats... A Great Hunt is over and the Space Wolves gather in the Fang to celebrate their victories and tell tall tales of their exploits. But one company has failed to return: that of the Great Wolf, Logan Grimnar. News of his death sends the Chapter on the hunt for the truth, with Ulrik the Slayer at their head. As they fight their way across the galaxy in search of their lord, the Space Wolves uncover a threat to the future of the Chapter itself.
