Curse of the Thirteenth Fey - Jane Yolen

You think you know the story of Sleeping Beauty, but the real story is far more spellbinding…

Gorse is the thirteenth and youngest in a family of fairies tied to the evil king’s land and made to do his bidding. When accident-prone Gorse falls ill just as the family is bid to bless the new princess, a fairytale starts to unfold. Sick as she is, Gorse races to the castle with the last piece of magic the family has left—a piece of the Thread of Life. But that is when accident, mayhem, and magic combine to drive Gorse’s story into the unthinkable, threatening the baby and the kingdom.
