The Sisters of Battle are the Emperor's most devout worshippers, fierce warriors preaching the purity of the Imperium and scourging their enemies with bolter and flamer. On a distant world, the Ecclesiarchy outpost of Sanctuary 101, was wiped out by an implacable foe - the fearless, soulless necrons. Now, a mission of the Sisterhood has returned to reconsecrate the site - but the metallic nightmares still lurk in the darkness, guarding a secret that has lain dormant for millennia. A vicious battle will be fought - one that can only end in the total destruction of the unrelenting xenos, or the annihilation of the proud Sororitas.
