Tik-Tok of Oz by L. Frank Baum audiobook.
In this really exciting and well written story of Oz, the Shaggy Man is on a quest to find his long lost brother. But all does not go smoothly. Oh no. Because his brother is being held prisoner deep underground by the evil, grumpy and not very nice King of the Gnomes, Along the way to find him, he is joined by Polychrome, a Daughter of the Rainbow (a fairy), Betsy Bobbin (a human girl), Hank (a small mule and Betsy's faithful protector), Tik-Tok (the famous wind up mechanical man), the Rose Princess (an ex fairy who is now a mortal), Ann (the Queen of the Oogaboos on her way to conquer the world), her army (17 officers and one private, File), a tunnel through the earth, the famous and all powerful Jin-Jin and last but definitely not least, Quox (a young dragon who talks funny and was great fun to read). The scrapes and adventures this motley crew get into are enough to fill a book. And this is the book. Listen and enjoy!!
