Sleeping Beauty's Revenge

Stella comes back to the Lawsons as their daughter, and Luna, who was adopted and grew up with three brothers who doted on her, becomes the stand-in. She is blamed for things she has not done and the house takes Stella's side each time. The eldest brother is running a study on long sleep and Luna signs on as a volunteer for it. Before she goes under she donates her corneas to the brother who is blind. The sleep is set at thirty years. Once she is gone the Lawsons learn that Luna was the daughter they had lost and that Stella had been passed off as her, and the three brothers are left with what they did to her. She wakes at the end of the thirty years with nothing of her life before it.
