When word reaches him of turmoil on his adoptive home world, he orders the Iron Warriors to abandon their campaign against the xenos Hrud and crush this emerging rebellion by any means necessary...

As religious war spreads across the planet, spearheaded by the Brotherhood of Lorgar, the Primarch is plagued by visions of the future and the coming of the Emperor.

Despite his self-imposed isolation, others in the brotherhood of Primarchs seek to draw him into the greatest ideological battle of them all – the place of psychic power within the Legions.

At the height of the conflict, at the void-city of Zenith, a dread bio-weapon from an ancient time is unleashed. At once, the Imperial force is brought to its knees, as allies are turned against each other and the Raven Guard left to face almost insurmountable odds.

The eleventh book in The Primarchs, Angron - Slave of Nuceria is written by Ian St. Martin and focuses on Angron, Primarch of the World Eaters Legion. As the Emperor travels the galaxy at the head of his Great Crusade, few events are as important as rediscovering his scattered sons, the Primarchs, and bestowing them as the masters of their Legions. United, a Legion becomes a reflection of its Primarch, both in his strengths and his flaws. For the XII Legion, once the War Hounds and now the World Eaters, the line between strength and flaw is almost impossible to separate. Placed in command of a Legion he does not want, in service to a father he cannot forgive, Angron gives an ultimatum to his children, one that will set them down a path that they can never return from. So desparate for his acknowledgement, will the World Eaters follow their father and cast themselves in his broken image or will they resist? And will any of them ever learn who their father was truly meant to be?

12. The Horus Heresy - Primarchs Book 12: Konrad Curze - The Night Haunter

Of all the Emperor's immortal sons, the Primarchs, it is Konrad Curze whose legend is the darkest. Born in the shadows of Nostramo, a world of murderers, thieves and worse, is it any surprise that he became the figure of dread known only as the Night Haunter? Heed now the tragic story of the creature Konrad Curze, master of the Night Lords Legion, of how he became a monster and a weapon of terror. He who once served the Imperium saw the truth in a maddening universe and the hypocrisy of a loveless father, and embraced the only thing that made any sense -- Chaos. From the blood-soaked gutters of his Hive World upbringing, to the last days of his ill-fated existence, Curze is a Primarch like no other and his tale is one to chill the very bone...

13. The Horus Heresy - Primarchs Book 13: Lion El'Jonson - Lord of the First

The thirteenth book in The Primarchs, Lion El'Jonson - Lord of the First is written by David Guymer and focuses on Lion El'Jonson, Primarch of the Dark Angels Legion. Each primarch is an exemplary being, derived from the Emperor’s own genetic stock to embody a facet of His personality. Their powers are unfathomable, but only one of them is the First. Lion El’Jonson is the paragon of what it is to be a primarch. His Legion, pre-eminent for most of their long history, typify the virtues of temperance, pride, and martial excellency that the Lion embodies. They are the Emperor’s last line and final sanction. They are His Dark Angels.

14. The Horus Heresy - Primarchs Book 14: Alpharius - Head of the Hydra

The fourteenth book in The Primarchs, Alpharius - Head of the Hydra is written by Mike Brooks and focuses on Alpharius, Primarch of the Alpha Legion. Legend abound of the glorious - or infamous - deeds of the Emperor's sons. Yet almost nothing is known of Alpharius, the most mysterious of them all, for the Lord of the Alpha Legion is unparalleled in the art of obfuscation. Such are his gifts of secrecy and deceit that even his rediscovery has remained an enigma - until now. But when the tale comes from the serpent's mouth, where does the deception end and the truth begin?
