The moment psychic detective Pixie Tate steps inside the opulent Aldershoff Hotel in Manhattan, one of the last relics of New York's Gilded Age, she senses instantly that a dark spirit is wreaking havoc within its elegant walls. Pixie knows that she must use her unique gift to travel back in time in order to discover the secrets of the past, and as she slips back over a hundred years, she's shocked to find herself in the midst of one of the most famous events in history. As the stars twinkle overhead, Pixie realises that time is running out. But when she comes face-to-face with a man she'd thought lost forever, will she keep her promise to save only the souls she should - or is it too late, and has she already changed the future?
