Fifteen-year-old Morgan Lefevre is mistaken for one of her ancestors while visiting Tintagel, King Arthur's birthplace in England and she is summoned through time to the alien world of Nwm. With her only companion, the boy Arduu, she is caught between the opposing cruelties of the two Magics, the Circle, and the Line, who have been fighting one another over the centuries and across many worlds. When Morgan and Arduu gain possession of an ancient sword of the Third Magic, Earth itself is drawn into the struggle. Times and worlds merge as Morgan is brought face to face with her own destiny.
