This seemed like a connector book. There was no clear plot and no clear thesis to the book, other than to bring back all the old characters back together and to introduce new characters who will be prominent in future works. If you're reading through this series, I don't see much of a point to reading this one, unless you just cant get enough of OZ. There is also the questionable inclusion of Santa Claus, which could only be described as a stretch to inspire more of an idea of a fairy land. It will be interesting to see where he goes from here in the series.
