Horus Heresy - Warhammer 40,000 EBooks

The Horus Heresy is a series of novels, anthologies and audiobooks based on the historic events known as the Great Crusade and the Horus Heresy. The novels are written by different authors, but follow the same storyline - the fall of Warmaster Horus and his campaign of treachery to usurp the Emperor as ruler of the Imperium.

The publishing order of the books does not reflect an attempt to tell the overall storyline chronologically; the stories are set are various points within the overall meta-plot, gradually illuminating the whole tale from various perspectives. There are directly connected works within this structure, however; the first three novels are a distinct trilogy, the eleventh is a sequel (of sorts) to the sixth, and the 12th and 15th are intended by the authors to be a duology.
