In a cathedral at the south of the Istryan Empire, young men and women are trained to be killers. The Order of the Golden Sword's inquisitors are feared for their brutality masked as piety. Masters of blade, poison, and crossbow, their quarry is the god-cursed werewolf, whom they hunt with impunity to herald the return of their god.

Betrayed by her monstrous father, Selene loses her left arm and nearly her life when she's saved by a traveling inquisitor. Scarred and broken, she swears vengeance on the cursed beasts and joins the Order. It takes all her will to overcome her limits, only for her violent past to drag her back into blood.

With the fabric of the empire at stake, Selene must master her hatred, hone it to a sharp point, then let it loose on her enemies.
