The fourth installment of the successful series of fictional boy wizard is certainly large (almost 800 pages) but it is very well written (it is far from basic language and little expanded first novel.) Accessible Speaking and reading the English fluently, it will be much harder to decipher for those who do not have sufficient fluency in the language of Shakespeare and Stevenson. But I still recommend this suspenseful novel of twists, humor and courteous charm! One of the best novels of Harry Potter in my humble opinion!
