What happened to Four’s personality? Better yet, what happened to that really cool heroin in the first book? Tris became annoying at times. If I had not known their personalities in the first book I'm sure I would have enjoyed them. But going from such great characters to the ones in this book made it hard to love them. Also still shaking my head a little on how some of the things in the book would work. Slow starting again, but the end was great - just like the first book.
