The Siege of Terra is a direct continuation of the original Horus Heresy novel series.

The Siege of Terra will detail the final events of the Horus Heresy, most notably the eponymous Siege of Terra and the final duel between Horus Lupercal and the Emperor of Mankind.

1. The Solar War

The Solar War is the first novel in the Siege of Terra series and is written by John French. After seven years of bitter war, the end has come at last for the conflict known infamously as the Horus Heresy. Terra now lies within the Warmaster Horus' sights, the Throneworld and the seat of his father's rule. Horus' desire is nothing less than the death of the Emperor of Mankind and the utter subjugation of the Imperium. He has become the ascendant vessel of Chaos, and amassed a terrible army with which to enact his will and vengeance. But the way to the Throne will be hard as the Primarch Rogal Dorn, the Praetorian and protector of Terra, marshals the defences. First and foremost, Horus must challenge the might of the Sol System itself and the many fleets and bulwarks arrayed there. To gain even a foothold on Terran soil, he must first contend the Solar War. Thus the first stage of the greatest conflict in the history of all Mankind begins.

2.The Lost and the Damned

The Lost and the Damned is the second novel in the Siege of Terra series and is written by Guy Haley. On the thirteenth day of Secundus, the bombardment of Terra began. With the solar defences overcome through the devastating strength of the Traitor armada and the power of the warp, Horus launches his assault on the Throneworld in earnest. After withstanding a ferocious barrage of ordnance, an immense ground war commences outside the Imperial Palace with every inch gained paid for in the lives of billions. The front lines are beyond horrific and the very air is reduced to poison and blood. Bodies are thrown into the meatgrinder but the outer redoubts cannot possibly hold for long, even with the loyal Primarchs to reinforce them. For Horus has his own generals to call upon. Between the plague weapons of Mortarion and the fury of Angron, the defenders face a losing battle.
