It is the duty of the Astra Militarum to ensure the alien and the heretic alike are put to the sword, and the worlds on which they fight are often as dangerous as the foes themselves. 

This collection of novels and short stories from across the front lines of the Astra Militarum includes the novels Death World, by Steve Lyons, in which the iconic Catachan Jungle Fighters must fight a xenos threat on Rogar III; a crucially important general must be rescued from the t’au in Kasrkin by Edoardo Albert; and a sanctioned psyker must fight both prophecy and betrayal in Witchbringer by Steven B Fischer.
