Why I rated it 8.5: It was good enough to keep me reading despite my desire to put it down and go home. Further, it was consistent with the previous books, brought together themes, arcs, and elements which were shown in previous books, and did so in order to move the book to a proper ending.
Further, I read it in 2.5 hours without a break; normally that large a book takes me 5.
