Defenders of mankind - David Annandale

The Space Marines, mankind's foremost defenders, wage war in two epic tales of heroism and horror. In The Death of Antagonis, the Black Dragons battle a tide of walking dead that blight the face of a world. Fighting alongside the Inquisition and the warrior-sisters of the Adepta Sororitas, the mutated Space Marines find their allies as much of a threat as their foes. In Death of Integrity, two Chapters - the Novamarines and Blood Drinkers - come together to clear an ancient space hulk of alien invaders at the behest of the Adeptus Mechanicus. But something great and dark lurks at the heart of the drifting starship, something that threatens to tear both Chapters apart.
