This is a very interesting middle grade book. It has an outlandish setting and background that kids will love. The orphanage has a creepy but interesting vibe to it and the idea of there being a screw at the north and south pole is really interesting. The characters are all distinct and interesting with the secondary characters having distinct and interesting personalities. This is a book full of quirky and original characters. There isn't much action in the book but the unfolding landscape keeps the reader interested.
Appropriateness: There isn't anything in this book that would upset parents. There is absolutely no romance and although the orphanage is creepy and horrible there isn't any violence. The almost exclusively male cast makes this a book that young boys will enjoy. I would recommend this book to kids 10-14.
