If I could give any book more than 5 stars it would be this one. This is one of my favorite books from the whole series. Umbridge is one of the best antagonists from any book, and I hate her so much that I may actually love her just a little bit. And then there's Hermione who decides to break the rules by forming Dumbledore's Army. Even with the depressing end with Sirius, I can't help but love this book.
