91. Daughter of the Forest 3: Child of the Prophecy, by Juliet Marillier.

Child of the Prophecy is the third book in a planned trilogy that (I believe) has since expanded to contain several more books. It deals with Ciaran's daughter Fainne, and her manipulation by her wicked sorceress grandmother into bringing about chaos and despair at Sevenwaters as part of a larger plot to bring down the faerie folk for good. 

This book was much in the same vein as the other two, and reasonably enjoyable. Fainne is a bit annoying most of the time, and there are a few quite convenient events that prevent things from getting too out of hand. She's incredibly lucky in how things turn out, and it's fairly surprising that people both didn't suspect her earlier, and that her grandmother didn't use a more stringent method of controlling her. Additionally, I thought a few 'hidden' things were rather easy to spot, which ruined a little of the shock value of the ending. Overall, a decent book.
