Unlike many readers, I didn't mind the ending. I didn't love it, but I didn't think it was worth getting so upset over. However, it was the alternating points of view that really bothered me, mainly because the voices sounded so much the same that I had to check the name at the start of each chapter to see who was speaking. Considering how different the two narrators were, that shouldn't have been the case. I also really felt that Four didn't act in character. He became too wimpy and whiny, but maybe that was just because we were inside his head for the first time. I suspect Ms. Roth was rushed through this series once the first one exploded, and I still very much admire what she achieved with her series.
