Book excerpt: Definitive omnibus edition of James Swallow's popular Sisters of Battle series. The Adepta Sororitas, or Sisters of Battle, are the military arm of the Ecclesiarchy, and their remit is to prosecute the enemies of mankind with extreme prejudice. Uniquely among the fighting forces of the Imperium, all the warriors of this organisation are female. Clad in ceremite power armour and armed with an awesome array of wargear, they fight with fanatical fervor for the glory of the Emperor, scourging both xenos and heretic alike with bolter and flamer. This omnibus collects together James Swallow’s two classic Sisters of Battle novels, Faith & Fire and Hammer & Anvil, along with the prose version of the audio drama Red & Black and a new short story 'Heart & Soul', available in print for the first time.
