I recently got a copy of this little Oz book. I don't know much about the author, James E. Nitch, who wrote under the pen name Onyx Madden, so, really, I'll just do a straightforward review this time around.
Ozma decides she wants one last adventure before settling down as ruler of Oz, so she sets off with the Sawhorse in the clothes she wore as Tip to have an adventure in the Quadling Country. While there, she runs into a sky blue dragon named Quox.
The story is set after The Marvelous Land of Oz and manages to serve as a bit of a prequel to Ozma of Oz.
While the writing is good and the concept is nice, I found a major flaw: there is far too much exposition. Entire chapters are spent on Nitch's concepts for Oz, including an origin of the Nome King, who doesn't even appear in the story. An entire chapter is spent explaining a vendetta Quox has, which is resolved in a few paragraphs. Near the end, Glinda remembers Ozma's restoration by Mombi, which is then retold by Nitch in his own style. I confess to peeking at the end and thought that perhaps Tip's clothes had gradually changed Ozma back into a boy, especially when Glinda advises her to burn the clothes and never wear such things again. Since that wasn't the case, it was a little disappointing. To be honest, Ozma's trip isn't really an adventure at all, just a travelogue, explaining how Ozma obtained the Red Wagon and Magic Picture.
Would I recommend this book? It's worth a read to see how a fan might develop their personal version of Oz. But the real big feature of the book is the artwork by J. Noel. It is especially Neill-influenced and is excellent line art. Also, there are color plates that are actually mounted on pages. If the book is a travelogue, it's a pretty one!
Oh, and Ray Bolger (an old Scarecrow of Oz, he calls himself) wrote an introduction.
So, while the story isn't one of the most impressive non-Famous Forty + stories out there, I'd suggest picking it up.
