Adventures of boy wizard knows almost everyone. Character created by J. K. Rownling has gained immense popularity. However it's nothing surprising, confirm it unless everyone who gave sucked into the world of muggles and wizards and read books one after the other.
Even if you have not read the books, you probably watched movies based of the best-selling novel. If you're bored and you're looking what to do, our suggestion is to make a movie marathon of the cult saga.
Once again, listen to the arrogant expression of Draco Malfoy, feel the fear of He-Who-Must-Not-Be-Named. Look at the fate of three friends and remind yourself how beautiful Hermione Granger is! :)
