My oppinion about the book:
It was greatly written. That is a fact and i will argue with anyone that disagrees. But it left me with a few questions. I just wonder about the family tree of Harry as the name of his grandparents were never mentioned. I feel a sense of greatness and sadness that the series of ending and yes, i probably will cry when the movies of Deathly Hallows are released lol. But, anyways, what are some of your oppinions and questions?
