Harry Potter and the Deathly Hallows
CAUTION! DO NOT READ THIS POST IF YOU HAVE NOT YET READ THE BOOK!
I finished the book a few days ago. Wow! What a rollercoaster ride of a read it was! I was furious at several points and then finally happy in the end. I think Ms. Rowling could have cut out about 100 pages or added more action in the middle of the book. I'm kind of sad to see it end; though, I think she left it open ended on purpose, just in case she decides to write a new series based on the children or Harry as an adult.
I agree that the baby that was with Harry when he "died" was likely Voldemort's soul; however, this was, as far as I can recall, never confirmed. Jasonl and Maytagbear please correct me if I'm mistaken by siting the passage from the book that confirms this. Also, Jason1, to the best of my recollection, JK did explain how Harry got his scar in one of the previous books--I'm not certain, but I believe it was explained in the very first book. As I recall, it was explained that Harry was scarred when Voldemort tried to kill him. Someone please correct me if I'm wrong.
