Harry Potter and the Philosopher's Stone
Two of the most important ideas in this book are "Love" and "Self-sacrifice". It is important to the story that Harry grows up without any love in his life. His Aunt, Uncle and Cousin do not want him at their house, but would not send him away because they care about what their neighbors might think. Harry has never had any friends at school, because of Cousin Dudley. He does not know what it is like to have a friend, until he goes to Hogwarts and meets Ron and Hermione. Even though he is not used to trusting people, he very quickly learns to trust his friends.
