I was a little disappointed in the book at first. There seemed to be a lot of running around to no effect. However, once you get past that, the last few chapters make for one heck of a ride, pulling together most of the threads in the earlier chapters into one very satisfying whole. I practically squealed with boyish delight when I realized what Harry was about to do. It's one of those good HSQ moments that slams you in the gut with it's perfection. It also helps that the particular focus of the coming together is something that I've been photographed standing in front of along with some of my LJ friends. That's just... Neat.
I still think that there was some extraneous stuff that could've been discarded, but the ending let me forgive a lot of sins. Pity it'll never be filmed.
