"The Road to Oz" is the 5th book in the beloved Oz series by L. Frank Baum. In this book Dorothy and Toto meet a new friend, the Shaggy Man, and she travels with him a short ways to give him directions. Unfortunately (or perhaps fortunately) they find themselves in a maze of magical roads and obviously very far from Kansas!
Not knowing what else to do; Dorothy and her companions start out along a random road to see where it leads. Before long they discover that the road leads to Oz, and that Princess Ozma is having a birthday! Dorothy and her friends decide to follow the road until they reach Oz, because Dorothy would love to see her friend again, and they know that Ozma would be able to help them reach home again.
As they travel to Oz Dorothy, Toto, and the Shaggy Man pick up some more companions and travel through yet more strange lands. Baum's capacity for coming up with new concepts is astounding! We meet fox people, donkey people, and a man who makes music whenever he breaths. Dorothy also becomes friends with the daughter of the rainbow.
