Don't worry...I'm not going to give out any spoilers. =)
LOVED LOVED LOVED IT!!!!!
I finished it yesterday. Since I started on Saturday afternoon, I only stopped reading for dinner, sleep, and Sunday morning yoga class. Oh yeah, and the occassional bathroom break. :)
When I have the time, I will probably re-read it just because there were so many things going on that I'm sure I missed some relevant details. It was like an emotional roller coaster, with many twists and turns. There were times where I think something is going to happen and I'm already crying reading into it, then it turns into something else. I'm so glad I didn't get spoiled from the beginning. Otherwise, I would have been cheated out of the experience.
I cannot wait when they make this book into a movie because it will be like non-stop action packed from start to finish. I just hope they make it longer than the last movie. If you think about it, HP fans are die-hard enough to stay in line for hours and hours (days even!) then spend hours more immediately afterwards reading the book non-stop. I'm sure making the movie a little longer won't stop them from seeing it. Hey, it worked for Lord of the Rings, I'm confident it's going to work for the HP movies. I just felt like the OOTP movie, although pretty good IMO, left a lot of details out and I hope they don't cheat us out of the experience for the 2 remaining movies.
Oh, and I think Molly Weasley had THE BEST line in the book. :)
