I finished book 6 tonight. The last 150 pages or so were great. Pretty exciting, intense stuff. I just keep thinking these books would be a lot better if she cut out about 100 pages from each one. But, yeah, book 6 was great. I'm now ready to finish the series.
As I've read the Harry Potter books, I've taken about a 6 month break after each one, but I may try to read the last one fairly soon. I just don't normally read a lot of fiction, in fact I don't read any at all.
I've heard that book 7 is great from several people. I'll have to borrow it from somebody fairly soon.
