Cinders and Sparrows [Bachmann, Stefan]

Twelve-year-old Zita, an orphan and a housemaid, has resigned herself to a life of drudgery when a strange letter arrives, naming her the only living heir to the Brydgeborn fortune. Now the mistress of the castle, Zita soon realizes foul play led to the death of her family. And as she is guided through lessons in the art of witchcraft by the somewhat mysterious Mrs. Cantanker, Zita begins to wonder who is friend and who is foe.
