Sherry Alston was never told about her half-sister, Miranda. Yet soon after Sherry arrives at her Aunt Judith's house, she somehow begins to learn of the dead girl's secrets. Lindsey and Tammy, who live next door, decide to keep an eye on Sherry. Gradually, they too begin to feel Miranda's presence. As the unexplainable incidents multiply, Miss Judith convinces her brother to try communicating with his daughter's spirit through a medium. Tammy and Lindsey, suspicious of the famous medium, unmask her powers only to find that there are deeper mysteries still. This is a haunting story of two half-sisters, trying to declare their need for love and recognition. The eerie mood of mystery that surrounds the Alston family is perfectly captured in Trina Schart Hyman's illustrations. Trina illustrated children's books for over thirty years, receiving the Caldecott Medal for Saint George and the Dragon. A new afterword provides an in-depth look at the author's life.
