As a teenager, Vickie Preston survived an attack by a serial killer. That was the first time she saw a ghost. Now the city of Boston is being terrorized—someone is kidnapping women and burying them alive, but cruelly leaving a glimmer of hope for the authorities by sending a clue about their location. Vickie is pulled into the investigation when her name is mentioned in one of the notes. And as a historian, she has the knowledge to help uncover the graves the killer known as the Undertaker is choosing. But she also has another, unique lead: the spirit of one of the victims is appearing to her in dreams.
