Mary Rose
This is the fictional story of Mary Rose, a girl who vanishes twice. As a child, Mary Rose was taken by her father to a remote Scottish island. While she is briefly out of her father's sight, Mary Rose vanishes. The entire island is searched exhaustively. Twenty-one days later, Mary Rose reappears as mysteriously as she disappeared…but she shows no effects of having been gone for three weeks, and she has no knowledge of any gap or missing time.
