Synopsis
Baal is besieged. The tendrils of Hive Fleet Leviathan have reached the home system for the Sons of Sanguinius, and Commander Dante, calling upon the Ninth Legion's successor Chapters, is the only thing stopping the Great Devourer from consuming the Blood Angels’ home world. But in order to overcome the insidious xenos, Dante and his Blood Angels must also face an enemy within – The Flaw, a curse in their veins that they must counter if they are to reach their former glory. Can Dante defend Imperium Nihilus from enemies far greater than the Tyranid swarms that once threatened their home world? Or are the sons of Sanguinius doomed to succumb to the darkness in their blood?
