As a big fan of English, I could not pass up these books original release. The scenario I think everybody knows the movies with, so I will rather say that it is a great exercise for anyone who wants to read a book in English. The terms are simple and understandable, there is certainly the words 'invented' and relating to the HP universe. But overall it's a series of books whose difficulty and really progressive and constant. If you want you launch go ahead with closed eyes and you will see that read in original version is really great, you get even more appropriate the characters, dialogues etc ...
