Okay, I just have a few things to say about Half Blood Prince, for now. They aren't *real* spoilers, but I'm cutting them anyway.
1) ZOMBIES???
2) Why did she use the word "ejaculated" again? She should totally know better.
3) Why does Harry immediately jump to the conclusion of cousin-lovin?
4) Romantic subplots are nice, and I know that their hormones are raging, but *damn*. About 75% of this was romantic, I swear. It gets boring, JKR.
Oh, and killing Mr. Weasley? Totally not cool.
EDIT:
Oh, and by the way, Harry... you can make full use of the prefect's bathroom now that you're captain.
