After finding herself locked up in a dungeon on Christmas morning, she vows to take O'Malley down. Between trying to have a normal life in high school, and fighting various fairy tale creatures thrown in her way, Megan barely has time breathe. But when a mysterious darkness begins to snatch the fairies and leprechauns that have protected Megan and her family, she must learn the history of her luck and defeat the bad guys once and for all. This is the thrilling third book in the paranormal fantasy series, following STOLEN LUCK and TWIST OF LUCK.
