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 for her working-class origins, and mourns for her sister, who died not long after she was sent away. Hope comes in the form of a new teacher, Miss Emily White, but almost immediately, suspicions are raised that she is not all she should be. Ivy is captivated, yet as her devotion grows, odd reports begin to circulate that Miss White has been glimpsed in the garden picking flowers whilst also teaching a class, leaving the school but stalking the halls at the same time. 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.
