About Siege of Terra

The galaxy is in flames. The Emperor’s glorious vision for humanity lies in ruins. His favoured son, Horus, has turned from service to the Imperium and embraced Chaos. His armies, the mighty and redoubtable Space Marines, are locked in a brutal civil war. Some remain loyal to the Emperor, whilst others have sided with the Warmaster.

Pre-eminent amongst them, the leaders of their thousands-strong Legions, are the primarchs. Magnificent, superhuman beings, they are the crowning achievement of the Emperor’s genetic science. Thrust into battle against one another, victory is uncertain for either side.

After seven long years of bitter fighting, Horus has finally reached Terra. Suffering and damnation await all should the Emperor fall and the war be lost. The end is here. The skies darken, colossal armies gather. For the fate of the Throneworld, for the fate of mankind itself…

The Siege of Terra has begun.

After years of devastating war, Horus and his forces have arrived at Terra. But before they can set foot on the Throneworld, they must first break the defences of the Solar System. Powerful fleets and cunning defences bar their path – but can anything hope to halt the advance of the Traitor armada?

The Solar War is the first of the eight novels in the Siege of Terra. It charts the fortunes of Horus’ forces as they begin their assault on the defences that the protectors of the Solar System have put in place to defend mankind’s home world.

The action encompasses void war between mighty battleships, boarding actions and the traitors attempting to conquer Luna as a launching point for the invasion of Terra itself. Horus’ speartip, led by the indomitable Abaddon, meets the forces of the White Scars and Imperial Fists as battle is joined.

At the heart of the conflict are the Emperor and Horus. Though neither yet takes to the battlefield, their influence, and that of the Chaos Gods who work through the Warmaster, lies heavy over all. Both know that their destinies draw them together, and that their clash will decide the war. But first, Terra must fall…
