And here's a tiny excerpt:
The Quadling Country is not the easiest place to travel in Oz. The country is rough and filled with dangerous peoples. With the Red Wagon and the Sawhorse, it was easy, but on foot the walking was rough and tiring.
The Wizard was, at heart, a very practical man when needed. However, his knowledge of magic helped him create shortcuts. If a stream crossed their path, he now had his buoyancy solution made from the Voe leaves to help him cross. So, being very careful to not exhaust their strength too soon, he and Button-Bright were making good time on foot.
