I'd be beating a dead horse if I said much more about this book other than that it's fantastic and without a doubt one of the best of the series. 
 And guess what? It's HAPPY. Everything about this book is so HAPPY. I just love the way you always finish the last page with a big grin on your face, feeling like you are really at Hogwarts celebrating with Harry and the other students... 
 ...and then the Goblet of Fire comes along and crushes your soul. 
 Well, enjoy the happy moments while you can, right?
