Damn. Just finished Harry Potter 6, and am now singularly blue.
Can never make up my mind if those books are good or not, but was definitely enjoyable, and upsetting to finish it. The entire 600 pages was only about 4 hours reading time (somewhat disconcerting), but I think I am – much as I dislike re-reading novels – going to have to plough through the whole set before I read book 7.
