The Wonderful Wizard of Oz (Oz #1)

Harry Potter thinks he is an ordinary boy. He lives with his Uncle Vernon, Aunt Petunia and cousin Dudley, who are mean to him and make him sleep in a cupboard under the stairs. (Dudley, however, has two bedrooms, one to sleep in and one for all his toys and games.) Then Harry starts receiving mysterious letters and his life is changed for ever. He is whisked aways by a beetled-eyed giant of a man and enrolled in Hogwarts School of Witchcraft and Wizardry. The reason: Harry Potter is a wizard!
