When Emily Plankhurst is visited by the ghost of Gabriel Graystone, and learns he was murdered, she knows she must find justice for him. The only problem is, Gabriel was killed a hundred years ago, shortly after he broke off his engagement to the daughter of a prominent Taos family, and there aren’t many other clues to go by in finding his killer. Emily, who runs a private research library—a place that’s known to harbor its own share of ghosts—teams up with Samantha Sweet and her daughter to investigate. As they delve into the case they discover that the story goes much deeper than a broken engagement or an old feud. There are hidden places in Taos that no one knows about, and plenty of ghostly old secrets. With danger lurking in the shadows, can they uncover the truth before those secrets catch up with them?
