The Mysterious Window

Laura's twenty-eight years old. All her life she's seen people that weren't there. Her mother referred to it as sin. The priest referred to them as spirits. Her sister referred to her as crazy. Marianne referred to it as a gift. What happens now when a four-year-old spirit asks for her help and is followed around by the same demon that possessed Laura's body sixteen years ago? Does Laura help her or does her mother's perseverance convince Laura to leave well enough alone?
