Magic Below Stairs — Caroline Stevermer

Frederick is plucked from an orphanage to be a servant to the wizard Lord Schofield. Is his success on the job a sign of his own magical talent or the work of Billy Bly, the brownie who has been watching over him for years? No matter, for the wizard has banished all magical creatures from his holdings. But Billy Bly isn't going anywhere, and when he discovers dark magic within the Schofields' manor house, it's up to Frederick and Billy to break the curse - and keep the Schofield family safe.
