Harry Potter and the Half-Blood Prince

What am I supposed to say...? How do you review this story and do it justice? I suppose, given the emotional hangover I'm currently experiencing, my thoughts will be a brief summary:

1) Holy Smokes.
2) I saw it coming, and I still couldn't handle it.
3) Whatver development we get had better be good. Also, the last shred of hope I have, rests on the belief that Dumbledore anticipated the whole affair and things went exactly according to plan.
4) This book was awesome. I love a good, devistating, gut wrenching, climax.
5) Now, leave me alone. I have to read book VII.
