The first book Harry Potter and the Philosopher's Stone introduced Harry to a new world where children were still children even though their world involved flying on broom sticks, learing and making potions and casting spells. Around all this was Harrys' extordinary history as the one who survived and somehow defeated "the one who must not be named" Voldemort. Even in this new place there are children and teachers who either do dislike Harry or appear to do so.Harry makes friends and helps prevent a disaster all in his first year and with all this he finds a love of Quidditch - go for it Harry!
