I enjoyed The Marvellous Land of Oz
more than the first book in the series, The Wonderful Wizard of Oz.
This is probably because when reading the first book, I was comparing it to the movie, and found it lacking - and quite violent.
The second book in the Oz seies is much lighter, the characters are quirky, and was overall simply fun. There was Jack Pumpkinhead, an army of pretty little girls who conquer the Emerald City with knitting needles, as well as the Scarecrow and a much kinder and less murderous Tin Man.
