Seventh

As a third generation seventh child, Crystal knows better than most how dangerous fairies can be. Now, thanks to a fairy's meddling her brothers are in danger.

Lucinda, Queen of the blood fae, has claimed Crystal's brothers. Their freedom may be regained, if Crystal is willing to trade them for the items Lucinda needs.

Six items traded for six brothers, and a seventh trade for her own freedom. Escaping from the underground realm of the fae might well require the help of another fairy. A fairy who knows the shadows just as well as Lucinda does. One who stands to gain just as much from Crystal's entrapment as they do from her freedom.
