Gutterwitch

Scullery maid Joan has always known her place. Bound in service to a powerful witching house, she is maid and companion to Belinda, their treasured heir. But when she stumbles upon a fallen star and makes an impossible wish, she becomes a most fearful and forbidden thing: a witch with wild magic. For years, Joan hides her power, but when she and Belinda are invited to study at an elite university, she is swept into a world of ancient academia, ruthless politics, and powerful magic.
