Theme: You should be who you want to be and not depending in Society. 
The theme means when someone is making you do things that you would not like to do you are being not yourself, you should not do this stuff only to fit in society. You are who you are, and you also think what you think no matter what other people think about you. If you are yourself people will like you of how you are not for something you are not. Be yourself. This what my theme means. The theme is related to the book because in the novel when people become 16 they make them to do a surgery to become pretty to fit in society.  This is what my theme tells is that in not about if you are pretty or ugly is that you should be acceptedby who you are.
