This is the fifth book of the Oz series. There are a many roads converging at the same place, so that Dorothy and the Shaggy Man, who brushes his hair and beard in the wrong direction so as to look even more shaggy, are not at all sure which one to take. They finally start out along the seventh road because "seven is a lucky number for little girls named Dorothy", and this eventually takes them into the enchanted domains of Oz. On the way, they meet Button-Bright, a lost little boy from Philadelphia, and Polychrome, the Rainbow's daughter, also lost because she danced too far over the arc of the Rainbow and slid off the end. As Dorothy and her friends travel on their way to the Emerald City, the color of the paper on which the book is printed changes to indicate their passage through the various parts of Oz and the surrounding countries. The story culminates in a great festival held in the Emerald City to celebrate Ozma's birthday, at which we meet all the great personages of Baum's fairyland, many of whom have been interpolated from writings other than those about Oz.
