Horus Heresy. Book III: Legion. The Battle for the Abyss. Mechanicum

Not every battle of the great Heresy is noticeable to the eye and makes it to the pages of history. The warriors of the mysterious Alpha Legion, who once exterminated the Emperor's enemies not only with blades and weapons but also with lies and deceit, equally unobtrusively and insidiously turn against him. Genius, yet self-absorbed and greedy for knowledge, the adepts of the Mechanicum side with Horus, who has bestowed upon them dark gifts, and create unique war machines for Lupercal – from battle vehicles with artificial intelligence to starships of unprecedented power. As the internecine battles engulf Mars itself, truths buried millennia ago emerge, capable of shaking the entire galaxy... The third volume of the 'Horus Heresy' includes the novels by Dan Abnett 'Legion', Ben Counter 'The Battle for the Abyss', Graham McNeill 'Mechanicum'.
