Omnibus collection of a host of great novels focussing on the Adepta Sororitas faction in Warhammer 40,000.Among the blessed ranks of the Adepta Sororitas there are those whose legends and deeds endure for millennia. Saints, both living and dead, whose radiance instils hope and courage in the ranks of the God-Emperor\'s armies. Here, the glorious conquests and agonising losses that earned these holy warriors their sainthoods are retold. The Triumph of Saint Katherine tells the tale of this most holy procession, and how it inspires those on the battlefields of the Imperium to victory against all odds. In Celestine: The Living Saint, we follow Celestine beyond the veil of death and back again to answer the God-Emperor\'s call. And in Ephrael Stern: The Heretic Saint, a maligned Sister of Battle is faced with the possibility of the ultimate darkness - the loss of the Imperium itself.
