In the grim nightmare future of the 41st Millennium, the witch-hunting zealots of the Sisters of Battle stand between Humanity and damnation. From the elite Seraphim warriors to the berserk Sisters Repentia, they are the strong arm of the Ecclesiarchy and the scourge of witches.

When dangerous heretic psyker Torris Vaun escapes from her custody, Seraphim Miriya is disgraced in the eyes of her fellow sisters and superiors. Following Vaun's trail to the planet Neva, Miriya takes her sisters in pursuit and, along with Hospitaller Sister Verity, starts her investigations. When they uncover a terrifying plot that could threaten the future of the Imperium, will Miriya's and Verity's faith be strong enough for them to triumph?

Written by James Swallow.
