Better known for his Warhammer novels, Darius Hinks turns his attention to 40k with Mephiston: Blood of Sanguinius, a story that’s ostensibly about the Blood Angels’ Chief Librarian’s battle with his own power and nature. When young Lexicanium Antros witnesses Mephiston’s facade of control start to crack, the threads of their fates become entangled, and Antros finds himself accompanying Mephiston to a strange, embattled shrine world. The Blood Angels must journey across a world whose population has been twisted against each other, hoping to find a singular relic that might hold to the key to truly unlocking Mephiston’s power.
