The good girl has become the big bad wolf...

Rylie survived a werewolf bite. She's moved to her aunt's ranch to enroll in a new school and continue her life—except now she transforms into a monster every moon and struggles to control her murderous urges.

Without many werewolves left, it's hard to stay in hiding. A family of hunters–Eleanor, Abel, and Seth—recognize the signs and follow Rylie to her new home. They want to stop her before she murders someone, and the only way to do it is with a silver bullet. Seth soon realizes the werewolf is Rylie, the one monster he failed to kill. Worse yet, he's still in love with her.

Torn between family and love, Rylie struggles to reconcile her feelings and control the wolf within while Seth fights to do what's right. But what is right—obeying desire or duty?
