While doing research for a book on the paranormal, anthropology professor Emily Campbell investigates recent events at a New York City day care center. Her findings, along with developments in her own life, cause Emily to question long-held opinions and to see her past in a new light. But Emily is not the only one whose world is changing. She is only one player in a drama that has been unfolding for centuries - a spiritual tug-o-war surrounding an ancient object with the power to transform the hearts of humankind. As Emily tries to understand the signs around her, others are attempting to make sure she never does.
