OT, Harry Potter, NOT a spoiler
I just finished reading "Deathly Hallows".
I feel sad, the series having ended with this book. Each time I finished reading one, I looked forward to the release of the next. Harry was among the few which I bought immediately after release, expensive hardback copies.
I'm sure these books will become classics. Someone might attempt to write a sequel, but no one could do the job that J.K. Rowling did.
It's like losing an old friend.
