Blond and beautiful Kayla Jesperson is on top of the world when she's hired as the Special Assistant to Congressman Tad Bristoll, a rich, handsome, and powerful politician with an eye for pretty women. Kayla's glamorous new life comes to an abrupt end when she's attacked by Tad's wife after a fundraiser. Kayla walks out of the hotel into a terrible storm -- and vanishes, leaving a crowd of suspects but no clues. After she disappears, Kayla's only contact is with her roommate, Bridget Deel, to whom she sends cellphone texts that read like brain-teasers. With help from a psychic, a fairytale dream, and the mysterious appearance of thirteen stones on her doorstep, Bridget finally decodes Kayla's strange messages. On a cold, gloomy day before Thanksgiving, Bridget secretly sets out to find the missing woman -- only to come face to face with the demon himself.
