OK there are no spoilers here but if you're protecting yourself from even the slightest chance of finding out something, then you shouldn't continue. Be warned.
So people... I just finished reading Harry Potter and the Half-Blood Prince! In about ten hours, non-stop, to be exact. This book seemed... different. It was almost like reading a fanfiction actually -- not because the book was bad, but because the writing style seemed to be somewhat different. I don't know if you get me. The book, overall, was really good but I admit I was getting bored during some crucial points in the beginning - but that's just me, because I was constantly shouting, "Screw Voldie and tell me if Harry and Ginny get together!". lol. But as I said... that's just me. We do get a lot of answers in this installment, but I still think we're left with a way number of questions. The identity of the Half-Blood Prince surprised me, I wasn't suspecting it, but I admit I didn't waste much time contemplating who the Half-Blood Prince might be... I made a few feeble guesses, that's all, but didn't count on them. I think I was more busy ripping apart Order of the Phoenix to find more quotes/evidence that leads towards a possibility of a Ron/Hermione, Harry/Ginny relationship. lol. I waste wayyy too much time on this.
So -- post your little thoughts. Keep in mind that it should be SPOILER FREE... do not give out information from the books, there are still some people out there who haven't gotten the copy of the book. Make sure!
