I believe this picture needs no introduction, J.K. Rowling, the lady behind Harry Potter. And also author of The Casual Vacancy, a crime story which will become a BBC series in 2014 (just in case you did not know that by now!)
I have mixed feelings towards the Harry Potter novels, till volume 4 I enjoyed reading them all, but afterwards they became too dark, too mature. In my opinion they lost its childish magic, what do you think?
