The Soul Drinkers Space Marines are outcasts from the Imperium, hunted down due to the physical mutation of their gene-seed. But in reality, none are more loyal to the Emperor of Mankind than the Soul Drinkers. Having stabilised their gene-seed, and brought a halt to their mutation, the Soul Drinkers start rebuilding their Chapter with new recruits. But the recruits have their own ideas - rather than protect the Imperium, they wish to wage war against it. With the Imperial forces and the Inquisition closing in on the renegade Chapter, can their commander Sarpedon rally his troops to face the true enemy?
