The first book in the Siege of Terra series.
After seven years of bitter war, the end has finally come for the conflict known as Horus Heresy. Terra now lies within the Warmaster's reach, Throneworld and the seat of his father's rule. Horus' desire is nothing less than the death of humanity's emperor and the complete subjugation of the empire. He has been consumed by chaos and has gathered a terrible army that he can use to carry out his will and vengeance. But the road to the throne will be difficult, as the primarch Rogal Dorn, praetorian and protector of Terra, mounts the defense. First and foremost, Horus must challenge the very power of the Solar System and the many fleets and fortifications that are set up there. To even gain a foothold on Terran soil, he must first fight against the Solar War. Thus begins the first phase of the greatest conflict in all of humanity's history.
