The Armour of Contempt

Colonel-Commissar Ibram Gaunt spent a year fighting as part of the underground resistance on the enemy-held world of Gereon. When he left, he promised that he would bring the forces of the Imperium to liberate Gereon’s citizens from their oppressors. 

Now he has returned, a crusade army at his back, but he finds a world devastated by war and a people irrevocably damaged by the taint of Chaos. Now Gaunt must fight to save Gereon not only from the enemy, but from the Imperium itself.

The Armour of Contempt is the tenth book in the Gaunt's Ghosts series.
