It's not possible for me to do a review for any of these books justice. I think I've finally come to that conclusion.
I remember being absolutely awe-struck and blown away the first time I read this. Rowling threw a twist in there that I never saw coming (still one of the few books to pull one over on me), and on re-reads I always marvel at how completely she set me up for that twist. I should have seen it coming, but I didn't.
That's just a small part of what makes this book my favorite in the series. It always has been. It always will be.
