She killed off my favorite character. D:
Who? I really doubt it was Crabbe, so... was it Dobby? Lupin? Tonks? Fred? Real shame she killed off Fred.
Well, what about Snape? Don't forget him. And he definitely has potential to be a favourite character. ;D
The only thing I would have to point out though, is that there is no Quidditch match whatsoever, and that's the only serious lack this book had.
Aw, c'mon, Quidditch really wouldn't fit in there. I mean, I'd even doubt there would have been Quidditch in that year, with all the terror at Hogwarts rising. Or should Harry have played some, secretly, while he was at Hogwarts? "Oh, I'm most likely gonna be killed very soon, let's play some secret Quidditch"? >_>
