Leslie Barnes has just moved to San Francisco with her younger sister and bought her first home. It seems the perfect place for Leslie and her sister Emily, a brilliant young musician...but as they move in, strange and unsettling things begin to happen. Apparently the previous occupants aren't quite done with it, despite the fact that the previous owner is dead. A professional psychologist, Leslie is in over her head when dealing with the occult--until she meets Claire Moffatt, a charming medium, and Claire's mentor, Colin MacLaren, world-famous psychic investigator. They will help, but Leslie must find abilities she didn't know she had to rid the house of the evil that is trying to use it.
