Soul Catchers - Carrie Pulkinen - Bog

Whoever kills the wolf becomes the wolf…
Wren Lewis shouldn't be alive. Magic is illegal, making her mere existence a crime, and if the government ever discovers the truth about her powers, she'll be killed on the spot. Or worse. But when she uses her magic to kill a wolf that's attacking her mom, her abilities are exposed and the animal's evil spirit possesses her. Unable to control the beast inside her, she flees the city in search of a cure before the wolf spirit consumes her soul, turning her into a murderous monster permanently.
