*sees an Oz book*
"Oh, cool, I loved this as a kid!"
*realizes I hadn't read this one*
"Wow, this is really boring and badly written"

In the intro Baum pretty much says that he was tired of writing about Oz, but got so many letters from kids asking for more that he ended up writing this book. It reads like he didn't want to write it, most of the book is all the old characters arriving and saying hello to each and every character.

The illustrations are great though.
