The legendary Commissar Ciaphas Cain, lauded as one of the great heroes of the Imperium, finds himself thrust onto the battlefield again. Cain wants nothing more than to keep out of trouble and get to the other side of his commission in one piece, but the war-torn 41st millennium has other ideas. Confronted with the powers of Chaos and hordes of alien foes, our intrepid Commissar seeks to sidestep danger and talk his way out of trouble. Yet each time he survives his legend only grows, and his life is in ever-greater jeopardy…
