Harry Potter is the main character of the great novel about his adventures in the Hogwarts School of Witchcraft and Wizardry. This novel was written by Joanne Rowling, who has become very famous all over the world after publishing the first book about young wizard "Harry Potter and the Philosopher's Stone". Some years ago she made a giant fortune, because "Harry Potter" was in great appeal among youth and adults.
Harry Potter lived with his uncle Vernon Dursley, aunt Petunia Evans and their child Dadly Dursley because his parents were dead in the accident, as the Dursleys said. But one day, when Harry was 11 years old, pretty normal Dursley's house was attacked by Hogwarts letters, which invited Harry to enter the school of witchcraft and wizardry. Harry suddenly found out that his parents were killed by the most powerful dark wizard of the 20th century! And he is very famous in the magic world as The Boy Who Lived, because Voldemort couldn't kill him for some unknown reason.
Here is the description of Harry Potter: "Harry had always been small and skinny for his age. He looked even smaller and skinnier than he really was because all he had to wear were old clothes of Dudley’s and Dudley was about four times bigger than he was. Harry had a thin face, knobbly knees, black hair and bright-green eyes. He wore round glasses held together with a lot of sellotape because of all the times Dudley had punched him on the nose. The only thing Harry liked about his own appearance was a very thin scar on his forehead which was shaped like a bolt of lightning."
Harry was a copy of his father with black tousled hair and only his bright-green eyes was as alike as his mother's eyes. That's why his parents' friends always compared him with his father.
"Harry Potter" is a genuine masterpiece of modern literature, that's why it is still read by children and their parents all over the world.
