I approached this book with trepidation and every intention of reading as slowly as I could. I had to put the book down every third chapter or so to make sure I had processed all the information. A couple of times, I went back and looked up stuff in previous chapters.
And since many of the people I know haven't finished this book yet, I'm not really giving anything like my normal review. I will say that I loved this book every bit as much as I loved the previous six.
Also, I want to say that I took a quiz on The Leaky Cauldron to predict what would happen in book 7--and I was oh-so-very wrong with most of my answers. It's probably a good thing that I never took the others. (I think there were two more.) Really, that just made the reading all the more fun--I like being surprised.
And I'd be more than happy to discuss this book with any other HP fans out there--I just don't want to post spoilers.
