I just got done reading the book. Yes, I am already done with it, though I just got it Friday night. I have pretty much been reading it since that time-any chance I got. It is 652 pages long, 30 chapters, but reads VERY fast. I will try not to divulge too much in respect to those who haven't finished it yet. There were MANY things that I expected to happen, but my suspicions and predictions of many of the characters AND events were either 100% dead on or 100% inaccurate. I will not divulge who the Half-Blood Prince is, but I will say this-He was my first guess after Harry received the ________ and what was in it----well, you'll have to read the book. I know I like the book 100%, but the ending I wasn't too keen on. Then again, I was definitely expecting something way different. Harry does have a little romance in the book, and if you read more into the little hints, particularly in the first couple chapters, you will be able to accurately tell who it is-and its not a surprise - I was hoping it would happen, as did most other HP fans. There were MANY answers to lingering questions in this book, and JKR does a very good job at incorporating most of those into a great series of events, and keep everything moving. Most of the book, we learn MUCH about Voldemort's past, how he grew up, and came to be what he is, AND we learn how he made himself immortal. We also learn more on WHY he went after Harry. Book 5 touched on it, but this one puts it more into perspective, with more background info. We also learn how Harry can defeat Voldemort. The only negative part that I do give it, is it starts out a bit slow, much like #4, the Goblet of Fire, going back in time describing past history, rather than starting at Privet Drive with Harry. But half-way through the 2nd chapter, it starts picking up. JKR actually has stated that the first chapter of this book, was actually slated to be the first chapter for the Philosopher's/Sorcerer's Stone. It would have made sense, but it would have also dragged that book down. The series gets darker and more scary as they go along, and since #1 is fairly light, this chapter really wouldn't fit. It would also give more away, too early, thus leaving less for the last two books. The Dursleys do make an appearance, as usual, but not so much this time. I kinda wished they would have been more present in the beginning, maybe Dudley getting bullied by Harry for a change, but ya can't have everything. Yes someone dies (actually, many people do, at the hand of Voldemort and the Death Eaters, which is a given), but the one I am talking about is a main character. It came as a shocker, and I actually cried when it happened. The person dies at the hands of another main character, which I was surprised at, but not surprised given past events and backstories. I guess, after all this time, after becoming kind of attached to the characters, I feel like someone I know and have grown fond of, has died. The next book is sure to be somewhat hard to read, given one of the main characters is gone, but I do want to see what happens in the end. I am not sure I will like the choice(s) Harry made at the end of this book, as it foretells what will happen in the last one. It is kind of saddening. But I am still looking forward to the last of the septology, nonetheless.
