The review below was based on my first read of the Harry Potter books, ages ago and in Dutch. Updated reviews will follow after a reread (in English) I plan to do.
The Prisoner of Azkaban was my favorite book of the series, so it’s obvious I didn’t like this one as much as I did the third. In my opinion it took too long before Harry and his friends are actually going to school again. And I always liked the schoolparts of the stories best. I liked the end of this book…
I thought you can really feel that Rowling is willing to make her books ‘darker’ and more sinister in comparison with the first books.
