Many young readers are familiar with the adventures of Dorothy, who is carried away by a tornado from Kansas to the distant Eastland, where the Tinkerbells live, who tell her about the land of Oz and its powerful wizard. The book Dorothy and the Wizard of Oz tells the continuation of the events of Dorothy and the Wizard from the previous book The Wizard of Oz. The plot begins with an earthquake in California, where Dorotka stopped for a short visit to relatives after returning from Australia. Dorothy is riding in a horse-drawn carriage driven by her cousin Zeb when the earth shakes. The earth cracks and everyone falls into the land of the Mongoose, and Dorothy experiences new adventures with old and new friends.
