Harry Potter is about an orphaned boy who discovers he is a wizard on his eleventh birthday and is invited to attend Hogwarts School of Witchcraft and Wizardry. He learns his parents were murdered by the dark wizard Voldemort, and that he is famous in the wizarding world because he was the only one to survive Voldemort's attack, which left him with a lightning-bolt scar on his forehead. The story follows his adventures at school as he learns magic, makes friends, and confronts the challenge of defeating Voldemort.
