WOW. I just finished it about half a hour ago.
This isn't a book review. This is just my first reaction and that reaction is that Harry Potter and the Deathly Hallows is the best of the seven books. Very exciting! The world went away as I read the last quarter of the book.
Many of the things I'd guessed would have to happen, did happen, but there were twists, so it was all that more satisfying that I didn't guess everything.
You have to read them all before you read this one. But you won't be disappointed when you get there.
WOW.
