Book 3 in The Horus Heresy: The Siege of Terra. Essential reading for all
Horus Heresy fans The war for the fate of mankind blazes on. Though the
outer defences have fallen, the walls of the Palace itself remain inviolate
as Rogal Dorn, the Praetorian of Terra himself, uses every known stratagem
and ploy to keep Horus's vast armies at bay. In Perturabo, the Traitor
siegebreaker, Dorn faces an adversary worthy of his skill. A terrible,
grinding attrition ensues. The crucial battle for the Lion's Gate spaceport
is at the heart of this conflict. With it in their possession, the Traitors
can land their most devastating weapons on Terran soil. Dorn knows it must
not fall. But with enemies attacking from within as well as without and the
stirrings of the neverborn drawn to the slaughter, can the Imperial
defenders possibly prevail?
