Got my HBP at 8+ this morning and didn't stop reading till 4 (with lunch in between of course). I liked it. Liked it more than book 5. It went very fast and I was satisfied. Still big question marks, but I am happy enough, because I will spend the next couple of years re-reading it and other people's theories until book 7 comes out.
I wouldn't say no to book 7 right NOW, though.
In other news, Reverbere was cool, and Ade Bay rocks. <3
