Necropolis (Novel)

Necropolis is the third volume in the Gaunt's Ghosts series of novels by Dan Abnett.

Synopsis
On the world of Verghast, a grinding war between two hive cities -- one loyal to the Imperium, the other fallen to the worship of the Dark Gods -- is bolstered by the forces of the Astra Militarum, spearheaded by the Colonel-Commissar Ibram Gaunt and the Tanith First-and-Only. But bitter rivalries and treachery threaten to derail the defence of Vervunhive, and it falls to Gaunt to take command of the Imperial forces and forge victory from an almost certain defeat.
