Now I'm depressed... and confused... who is the hero? who is the villan? who is to blame? what is "good"? what happened to everyone's heart? what was the point? 
 And most of all... is this really YA? when does a book stop being YA and start being Adult? is a book YA just because the main characters are young? Can a young teenager, 15 years old or less, enjoy, handle and GET everything that happened in the series? I think we need a new genre, people
