Deuce is a seriously tough girl to begin with and she starts off kind of mechanical, doing what needs to be done and feeling uncomfortable with any ideas that go against what she's come to know. However she is kind of forced to open her eyes and because of that she grows as a person, she starts becoming more of a human. She grows into a girl who isn't as confident as she normally is but she gains real emotions and real feelings, she develops empathy and learns when disagree with authority. Part of the reason her eyes are opened is because of Fade, the mysterious 'outsider' that lived in her colony and became her hunting partner. He's always been different than the other people in her colony because he didn't grow up with them and because of that he sets himself apart. He's a fierce fighter but as the book continues forward we get to see that he has far more humanity than most people Deuce knows. He challenges her to become stronger while at the same time making her break down the walls and feel what's happening around her. It's a really interesting juxtaposition for his character that I think really works. We get to meet some really interesting people along the way like Striker, who is a really rough character that I ended really hating. He made my skin crawl to be honest, but I like the way his character started to develop despite the short period we get to know him.
