The galaxy burns at Horus's command, and a billion more lives are lost with each passing moment - though it was t always so. Once, the title of Warmaster stood for hour, loyalty and a fierce pride in the strength of the Space Marine Legions. But perhaps by following the myriad lines of destiny and defiance that were already woven around the primarchs and their sons, we may yet come to understand the bitterness that can eat away at even the most steadfast of souls... This Horus Heresy anthology contains fifteen short stories by authors including Graham McNeill, Nick Kyme, Gav Thorpe, Chris Wraight and many more. It also includes Aaron Dembski-Bowden's acclaimed vella Aurelian.
