What if you grew up to realise that your father had used your childhood as an experiment? Rosemary doesn't talk very much, and about certain things she's silent. She had a sister, Fern, her whirlwind other half, who vanished from her life in circumstances she wishes she could forget. And it's been ten years since she last saw her beloved older brother Lowell. Now at college, Rosemary starts to see that she can't go forward without going back, back to the time when, aged five, she was sent away from home to her grandparents and returned to find Fern gone.
