Erica Ridley

A chilling Gothic horror novel set at a coed boarding school in Scotland, where a teen girl must not only fight against her monstrous male classmates but the monster growing within her after being cursed. Every wish granted comes with strings attached. That's how Catriona Cameron ends up with a scholarship to Floodbane Academy-an elite boarding school on the Isle of Skye she never applied to-where she'll be one of only six girls to enter the castle's unwelcoming halls.
She's not looking for trouble. But after a few male students violently attack and make cruel wishes about her, Catriona is cursed with devastatingly good looks, unpredictable new powers, and an insatiable hunger to devour anyone who preys upon women. As the cravings mount, so does the carnage. With every new taste, Catriona faces the possibility that she is becoming as monstrous as those she hunts.
Is slaying the wicked truly worth the loss of her humanity?
