I finished reading this a few weeks ago, and I don't know -what- you're talking about. I thought this was an amazing series, and I loved the ending. I remember reading it and being unable to stop crying for a while. I loved it, and I thought it was a really nice way to end the series. The ending was really realistic in that happy endings don't actually happen in real life.
I adore sad endings, so this made me happy.
It's definitely one of my favorite series.
