Pure of Heart — Danielle Parker

It's not easy being a werewolf. After claiming her first (and hopefully last) victim, Harper thinks she has it all figured out. Her job keeps her busy. Her family locks her up during the full moon. She's even friends with the local vet who is always armed with tranquilizers.
But her fragile grip on the situation can't last. Not when newcomer Emerson moves into Harper's small town and sets the wolf free. Now Harper must figure out what the wolf wants, and stop it before she ends up with more blood on her teeth.
