Warhawk: The Horus Heresy: Siege of Terra, Book 6 (Unabridged‪)‬

Siege of Terra, Book 6 

With the Lion's Gate space port taken by the enemy, Jaghatai Khan of the White Scars prepares a brazen gambit, but one of his former brothers rises to take up arms against him.

Listen to it because: the heroic and dynamic White Scars hurtle headlong into combat with the unyielding Death Guard. As brother battles brother, the fate of Terra itself hangs in the balance.

The story: the Inner Walls are breached.

Traitor vanguards tear towards the heart of the Palace, sensing victory. Desperate gambits are attempted: an unwilling saint is released into the ruins, as well as an enthusiastic sinner. A black sword rises, forged from spite, ready to create a legend. But amid the slaughter, Jaghatai Khan, Warhawk of Chogoris, prepares to launch the most audacious strike of the conflict. His goal is nothing less than the liberation of the Lion's Gate space port. Cut off from any help, he stakes everything on one desperate counter-offensive, launched against an old enemy who has been made far greater than he ever was before. As the White Scars ride out against the newly crowned lords of life and death, they know that defeat for them dooms not only the Legion, but Terra itself.
