A newly minted Commissar steps out of the Schola Progenium's crisp parade ground and into a posting with the Savlar Chem-Dogs - a penal legion with a storied past. Before long, he's tasked with leading a kill team on a crucial mission through Ork-infested territory. Chem Dog, by Callum Davis, is a brand-new Astra Militarum novel, where the outcome is anything but certain.
