Yes, I'm an HP fan. Shoot me.
So I've just finished read "Harry Potter and the Half Blood Prince" (Three and a half days. No non-stop, but I've been spending more time reading it then anything else). Some people may think the Harry Potter books are children books. Let me tell you: This book COMPLETLY eliminates that. It's three times more mature then the Order of the Phoneix. Seriously, every aspect was well done: The conspiracy which was fully revealed in the last few chapters, the little jokes that made the book a bit amusing. But mostly well done was the fact that Rowling made Harry and his buds teenagers. There's love, a lot more then in the Order of the Phoenix. Harry gets jealous, and I won't elaborate.
Dan, I'd expect you're reading this. You once asked me why Voldemoert turned evil. Read this book, it'll make everything clear. It reveals Voldemort's birth, life and transformation into that snake-humanoid-thing. Also reveals the secret of his immortality, and reveals much of his personality, which has an intresting note to it. Plus, Dumbedore's a lot more active in this story.
The story starts out with a rather odd note, which seemes odd at first when coming from an HP book, and ends with a really sad note, that makes you feel like Harry had gotten almost nowhere in terms of DOING, but he did discover something important. Almost everything that mattered to Harry was in a way lost. I'm really hoping to see the conclusion to this tale, and hope Rowling's writing (Whose style had imporved, too, in my opinion) would only improve in the seventh, final Harry Potter book.
