The settings in this book are described beautifully. There is such care to the details that it's not overwhelming but just right. Victoria and Elliot, characters who wouldn't normally meet, but under the circumstances do, go well together. They have fun, and you have fun reading about them. I thought the story might be loosely based on a ballet which is mentioned in it, but after researching that, I believe this is the author's own creation, which leaves me liking it all the more.
I find the story original even while, yes, it starts as a quest with rings. It is unlike the Lord of the rings trilogy and stands on it's own. Only thing I didn't like was there were times when I had to put the book down. For a children's book, I thought it got a little dark, but that could be me mirroring my own dark times in it. I was frustrated in a good way, because the reason I put it down was that the book would get so dark and end a chapter where I did not know how it was going to end. I worried whether I would get a nice ending or a sad ending. Overall, I would say that makes it a great book, and I think kids will love it.
