The Wonderful Wizard of Oz is a children's book written in 1900 by L. Frank Baum. It was originally published by the George M. Hill company in Chicago, and has since been reprinted countless times, sometimes under the name The Wizard of Oz. The story chronicles the adventures of a girl named Dorothy in the land of Oz.

　　Plot summary　　

　　Dorothy Gale is a young girl who lives on a Kansas farm with her Uncle Henry and Aunt Emily ("Auntie Em"), and her little dog Toto. (Although her last name is only revealed in later books in the Oz series.) One day a cyclone appears outside and before Dorothy can reach the storm cellar, the farmhouse is caught up in the cyclone and deposited in a grassy field in the country of the Munchkins. The falling house kills the Wicked Witch of the East, who had established a reign of terror over the Munchkins.

　　The Good Witch of the North comes with the Munchkins to greet Dorothy, and gives her the Silver Shoes the Wicked Witch of the East had been wearing when she was killed (her death is explained in The Tin Woodman of Oz as due to her being old and dried up before Oz became a fairyland). In order to return to Kansas, the Good Witch of the North consults a magical blackboard which recommends: "Let Dorothy go to the City of Emeralds" and ask the Wizard of Oz to help her. The Good Witch of the North also kisses Dorothy on the forehead, stating that no one will harm a person who has been kissed by her. On her way down the Yellow Brick Road, Dorothy meets some remarkable characters: she liberates the Scarecrow from the pole he's hanging on, restores the mobility of the rusted Tin Woodman, and encourages the Cowardly Lion to journey with her and Toto to the Emerald City. The Scarecrow wants to get a brain, the Tin Woodman a heart, and the Cowardly Lion courage; and they are convinced by Dorothy that the Wizard can help them too. Together they overcome a pair of ravening Kalidah and escape from a field of sleep-inducing poppies.……

　　This book will show all the readers the fantastic adventure of young Dorothy Gale and her dog, Toto as well as her strange friends.
