Astra Militarum: Auxilia is a Warhammer 40,000 novel from Black Library, published in paperback format, written by Russell Zimmerman.

Abhumans are pressed into service all across the galaxy, but they are rarely accepted by those with whom they serve, as useful as they are. This novel offers an unexpected perspective on the Astra Militarum, exposing the cracks beneath its seemingly strong foundation.

A young and brash Cadian, Castellan-Colonel Orysian Roane, was always content to leave the true burdens of leadership to others – that is, until his chain of command was suddenly shattered. Now he is forced to take charge of a ragtag auxilia built around a clan of despised abhumans. A clash of different cultures and tactical doctrines, the regiment is filled with failures, survivors, and veterans from every corner of the Imperium.

Overseen and openly loathed by a murderous commissar, and consistently ignored by the Departmento Munitorum, Roane struggles with the impossible task of hammering his unit into proper Cadian shape, while those around him would rather see it destroyed. But before Roane can find his footing, a broken world is plunged into civil war, and his auxilia faces a trial by fire. Will this be both his first and his last command?
