The Wonderful Wizard of Oz - An American children's novel by author L. Frank Baum (Broché)

Dorothy is a young girl who lives with her Aunt Em, Uncle Henry, and dog, Toto, on a farm on the Kansas prairie. One day, she and Toto are caught up in a cyclone that deposits them and the farmhouse into Munchkin Country in the magical Land of Oz. The falling house has killed the Wicked Witch of the East, the evil ruler of the Munchkins. The Good Witch of the North arrives with three grateful Munchkins and gives Dorothy the magical silver shoes that once belonged to the Wicked Witch.
The Good Witch tells Dorothy that the only way she can return home is to follow the yellow brick road to the Emerald City and ask the great and powerful Wizard of Oz to help her. As Dorothy embarks on her journey, the Good Witch of the North kisses her on the forehead, giving her magical protection from harm. On her way down the yellow brick road, Dorothy attends a banquet held by a Munchkin named Boq.
The next day, she frees a Scarecrow from the pole on which he is hanging, applies oil from a can to the rusted joints of a Tin Woodman, and meets a Cowardly Lion. The Scarecrow wants a brain, the Tin Woodman wants a heart, and the Lion wants courage, so Dorothy encourages them to journey with her and Toto to the Emerald City to ask for help from the Wizard.
