I went out yesterday morning and bought the new Harry Potter from the nearest Odessey. Though there were reports of people having to queue up to buy the book, I did not find anyone in the store when I got there.
The book is quite interesting. It is a tight and not-put-downable read. No digression from the main story. Though the ending is widely seen to be very sad and dark, it just tries to make you look forward to final episode.
