When her guardian father turns into a fearsome wukodlak and tries to kill Selene, she flees for her life. The beast severs her arm in the escape and she wakes up in a church dedicated to the God of Light, saved from bleeding out.

Hunters of the man-beasts, the god's powerful Order offer her an opportunity for revenge. She takes it gladly, even if they're very secretive, and very religious. Her determination gains her the attention of the toffs of the Order, who place her under the mysterious Sorenius. Sorenius has hundreds of wukodlak heads under his belt, but tempers flare during his extreme training. As they grow closer, their tempers aren't the only thing that ignites.

Selene lets go of her past and becomes a full-fledged Sword of the Order. Then she discovers that her childhood flame Tristain is a wukodlak. She must put aside her feelings and hunt Tristain, otherwise he'll slaughter innocents just like his father did. But when she sees him for the first time in years, old feelings come rushing back, and she uncovers the dark secret about the wukodlaks that has been kept hidden by the Order for centuries.
