The Road to Oz
When a shaggy man asks Dorothy the way to Butterfield, she walks with him and shows him the way. But then she finds she’s lost, as there suddenly are about seventeen roads leading from the place she and the shaggy man are. Dorothy, Toto, and the shaggy man take a road and eventually meet Pollychrome, the Rainbow’s daughter and Button-Bright. The five set out to get to Oz and celebrate Ozma’s birthday.
The first Oz book with the shaggy man. At Ozma’s birthday, there are many different characters, including Queen Zixi of Ix, King Bud and Princess Fluff, the Queen of Ev and her children. This is probably not one of my favorites, but it’s still a good book.
