It bothered me not to know whether "A" was a boy or a girl at his/her core but it bothered me more to not know how "A" came to be. I also felt like all of the other stories we were getting glimpse's of were left hanging. It seemed a lot to keep track of along with the complexities of the love story that was taking place. I'm a big fan of closure and I don't need a "Happily Ever After" ending but this one had me asking, "That's it? What happens now?"
