This has always been one of my favourites of the Harry Potter series, so when it came to rereading I was terrified that I'd hyped it up so much in my mind that it could only be a disappointment. It wasn't. I completely devoured this book and I don't think there's any other way to really read it. I mean, it's Harry Potter after all.
It did break my heart a little I won't lie. The last 100 pages or so had me going through a hurricane of emotions and I had to keep reminding myself that it wasn't okay to cry on a public bus over Harry Potter, even if the feels were getting to me.
This book is where the whole series really takes off. You meet Sirius and get to finally learn the real story behind what happened on *that* night when Harry got his scar. and you get to feel ALL THE RAGE against Wormtail aka Scabbers aka a total scumbag. I'd forgotten almost all of Lupin's backstory and that crops up too. And then there's the utter RAGE when Snape cocks everything up at the end. Also, did I mention Buckbeak?
If you're going to (re)read just one of the HP books, make it this one. It's the last in the series before the books get real long, and it's the most intense of the first three. I love it so much and honestly would read it over and over and over again.
