I'm not, because my book hasn't arrived yet. Silly of me to order from Amazon - I should have just gone out and bought one. Still, I have housecleaning to do to pass the time.
I'm a slow reader, and can't just drop everything to read HP, so even when it does arrive I don't anticipate being able to comment on it until at least mid week. It's going to be difficult, if not impossible, to avoid spoilers, but I'll try.
