So I just got finished with Daughter of the Forest and will take a shot at getting some discussion going. This particulare question is for before you start the book, or wherever you are now. Just don't put any spoilers for the book in your answer!
Marillier's book was based on the Tale of the Wild Swans, a well-known fairy tale perhaps best told by Hans Christian Andersen. Independent of this book, what do you remember of the fairy tale? Were there any themes or ideas?
