Banished from her parents’ farm to a boarding school for young ladies, Ivy feels utterly alone. In a crumbling and isolated seminary that has seen better days, she is shunned by the other pupils, and mourns for her sister, who died not long after she was sent away. Hope comes in the form of a new teacher, Mademoiselle Emélie Blanc, but almost immediately, suspicions are raised that she is not all she should be. Ivy, however, is captivated, and the teacher is the only one to encourage her artistic talent. Yet as Ivy’s devotion grows, odd reports begin to circulate that Mademoiselle Blanc has unusual powers. Soon Ivy’s fellow students are convinced Mademoiselle Blanc – Emily White – can appear in two places at once. As increasingly strange rumours abound, Ivy’s obsession spins out of control, and with Emily White’s future at stake, she will do anything to keep her only friend.
