If you've seen the 1985 movie Return to Oz you will no doubt recognise elements of this book. While the Gump and Pumpkin Head were pulled from The Marvelous Land of Oz (the previous Oz book.) Pretty much the rest of the movie was taken from this book. Ozma of Oz configure the perfectly peculiar style from the first two. As I suspected would be the case, also starts to tie loose ends together from the previous works so it definitely starts feeling like the series is one cohesive whole. Because so much of it was familiar from the movie it's hard for me to evaluate the book on its own merits. This is diffent from other adaptations because it wasn't a diet adaptation, so it's impossible to say "Movie did X better while book did Y better." and unlike WWoO the story isn't an institution. Ultimately it was an enjoyable entry.
