Harry Potter and the Philosopher’s Stone (Harry Potter No. 1) - J K Rowling

In the non-magical human world - the world of 'muggles' - Harry is a nobody, treated like dirt by the aunt and uncle who begrudgingly inherited him when his parents were killed by the evil Voldemort. But in the world of wizards small, skinny Harry is renowned as a survivor of the wizard who tried to kill him.
