Barbara Rowett, an American tourist visiting England, did not believe in such things as faeries, witches, or time travel, until she was thrust into early 18th century England after a freak auto accident. Her disappearance into the past sends her family members into a desperate search for her before she is lost to them forever. In the meantime, Barbara finds herself called upon to save a young boy stricken with polio before the World has learned how to treat this past (and future!) epidemic. And, in between, are faeries, witches and the Master of Time, who hold the keys to her return to her own century, but hold them as hostage until she can save young William from this deadly disease. But living in a time when the World had neither the knowledge or tools in dealing with the disease, how can she succeed before Time runs out?
