The Emperor's vision of mankind ascendant lies in tatters. But with Horus's rebellion spreading to every corner of the Imperium and war engulfing new worlds and systems almost daily, there are some who now ask: were the signs there to be seen all along? In these dark times, only one thing is certain - the galaxy will never know peace again, not in this lifetime or a thousand others... This Horus Heresy anthology contains twenty-one short stories by the cream of Black Library's authors, including David Annandale, Aaron Dembski-Bowden, John French, Guy Haley, Nick Kyme, Graham McNeill, Rob Sanders, Andy Smillie, James Swallow, Gav Thorpe and Chris Wraight.
