As the darkness of mankind's internecine war slowly consumes the galaxy, those who still serve the Throne are forced to fight for both their own survival and the continued existence of everything they hold dear. With the threat of the Warmaster Horus' fleet looming ever closer to Terra, if will fall to such heroes to halt the tide, but the enemies arrayed against them are powerful and the burden of loyalty is great... This Horus Heresy anthology contains two novella-length tales - The Wolf King by Chris Wraight and Cybernetica by Rob Sanders - as well as six short stories by popular Black Library authors including Dan Abnett, Aaron Dembski-Bowden, Gav Thorpe and John French.
