Harry Potter became an orphan when he was just a new born and went to go live with his aunt, uncle, and cousin who were horrible people that made him sleep in the tiny closet under the stairs. When he was eleven years old Harry found out that he was a wizard and he found out how his parents really died so Harry went to a special school called Hogwarts and he had to keep battling the person that murdered his parents but in the end he won and he finally got his “revenge”.

A big guy named Hagrid came and knocked down the door and took Harry Potter. He met two people Hermione granger and Ron Weasley, he got put in Gryffindor so did his friends. There was a bad guy and they took him down?
