A fairy tale fantasy about twelve sisters forced to dance every night from midnight until dawn in the palace of the King Under the Stone to fulfill the bargains made by their mother. Galen, a soldier who has returned from a twelve-years war to live with his aunt and uncle is given an invisibility cloak by an old woman to whom he was kind. After the eldest princes from all of the surrounding countries have died after trying unsuccessfully to find out where the princesses go every night, Galen is given permission to attempt to save them - even though he is just a commoner. Those looking for fairy-tale stories will enjoy this one because it tells a story they probably do not already know. Knitters will especially appreciate the role of knitting in the story and the patterns at the end of the book.
