Book 27 in Horus Heresy series (2013)
Publisher: Black Library
Far out on the Eastern Fringe, the realm of Ultramar stands alone. Having weathered the Word Bearers’ attack on Calth and the subsequent Shadow Crusade against the Five Hundred Worlds, the Ultramarines primarch Roboute Guilliman now draws all loyalist forces to Macragge as he contemplates a new future for mankind.
With the arrival of more and more fugitives from the war that has engulfed the rest of the galaxy, all distinction between friend and foe is lost – isolated from Terra by fearsome warp storms, is Guilliman making a bid for power to rival even the renegade Warmaster Horus?
Believing Terra has already fallen to the Warmaster, Primarch Roboute Guilliman founds the Imperium Secundus.
The unthinkable has happened – Terra has fallen to the traitor forces of Warmaster Horus! Nothing else could explain the sudden disappearance of the Astronomican’s guiding light at the heart of the Imperium, or so Roboute Guilliman would believe.
Ever the pragmatist, he has drawn all his forces to Ultramar and begun construction of the new empire known as Imperium Secundus. Even with many of his primarch brothers at his side, he still faces war from without and intrigue from within – with the best of intentions, were the full truth to be known it would likely damn them all as traitors for all eternity.
