Harry potter books are great because of the great fantasy and mythology which you can find in every line and each word of those books.
Rowling has created a fantasy for children even adults and he has made alive all of old legends and myths in a new shape. her job is great and I think people dont allow to affront them.
rowling has made alive her country's traditional and fairy stories which all are about sorcerry and magician.
its really a creative job. adorable!
