At the end of the Wizard of Oz, the Scarecrow was made King of the Emerald City, Tinman was made ruler of the Winkies, the Lion went back into the forest and Dorothy went back to Kansas. Frank Baum got a thousand letters from children wanting to know more about what happened in Oz. This is why this book and 12 more got written.
In this story we meet Tip, Jack Pumpkinhead, a live sawhorse, the Highly Magnified Woogle-Bug and the Gump. These new characters meet up with the Scarecrow and Tin Woodman. There is an evil witch Mombi who is aiding General Jinjur and her army of young women, no longer content to stay at home and do chores they overthrow the Emerald City.
Good witch Glinda comes to the rescue.
I liked this book better then the Wizard of Oz. The characters had more personality then in the Wizard of Oz. A nice continuation of the story.
