Blood Magic: Book One Of The Ballad Of Kirin Widowmaker (Bk. 1) - Matthew Cook

Her sister was murdered, and Kirin hungers for revenge. Using the power of her "blood magic," the young necromancer creates grotesque and inhumanly strong creatures by calling men's souls back into their dead bodies. These "sweetlings," as she calls them, are utterly devoted to her, and Kirin cherishes them as if they were her own children. But while fighting a bloody war against a relentless enemy, she meets Lia Cho, a beautiful and gentle woman who can call the power of storms… and soon, Kirin learns that there is more to life than pain and vengeance.
