Query: JKR's Best work yet!!!

I thoroughly enjoyed this book over all the previous. Like many, I had this preordered a good 8 months before it came out, and was waiting on pins and needles. I ready about 200 pages on Sunday, and finished the rest of it all on Monday.I won't get into spoilers for any who actually haven't read this yet, but I particularly enjoyed Dumbledore's history lessons with Harry about Voldemort's past. Another enjoyable addition in this book is all the romance going on. It adds plenty of spice to the series, and leaves the reader very curious. I can't wait until book 7! I'm sure all ready all 6 books straight through a few more times before Book 7's release.
