Horus Heresy. Book VII

"Unknowing Fear"
Unaware of the origins and spread of the Heresy, but somewhat puzzled by Horus's orders, the Primarch of the Ultramarines, Roboute Guilliman, returns to Ultramar with the intention of mobilizing his warriors to repel the massive Ork invasion of the Veridian system. At this time, the supposed ally of the Ultramarines in this battle, the Word Bearers Legion, organizes an invasion of Calth, the second most important world in the Ultramar system, scattering the fleet of defenders and destroying anyone who stands in their way. This is the worst scenario that Guilliman could imagine. This means his brother Lorgar has decided to put an end to their bitter rivalry in this mad way. But only when the traitors summon their demonic masters and hordes of Chaos crash down on the Ultramarines does Roboute realize how far his brother's madness has gone. He also understands that in this struggle, neither side will be able to win...

"Primarchs"
Created in the image and likeness of the Emperor, the primarchs have come to consider themselves princes of the Universe and masters of their own fate — they led the legions of Space Marines in the glorious conquest of the Galaxy, and no enemy of the Imperium could stand against them. Nevertheless, even among this legendary brotherhood, seeds of dissent were sown long before the greatest betrayal occurred and Horus ignited the flames of Heresy. This anthology collects four novellas dedicated to the powerful primarchs: Fulgrim, Lion El'Jonson, Ferrus Manus, and the twin brothers Alpharius and Omegon. And while the roles have long been assigned, the performers are yet to unleash a war that will forever change the face of the Imperium.

"Where Angels Dare Not Tread"
From the very first days of the Great Crusade, Sanguinius — the angelic primarch of the Ninth Legion — was among Horus's closest and most loyal brothers. However, all this time, his Blood Angels have been forced to hide a painful secret regarding their true nature. Horus becomes aware of the flaw within the legion, and the Warmaster hints to his brother that the key to the Angels' salvation can be found in the ruins of one of the conquered worlds. The Sons of Sanguinius throw themselves there without a second thought. And when Horus's betrayal becomes evident, the Blood Angels will have to confront not only the army of Chaos but also their own demons, which have broken free onto the plains of Signus Prime…
