It is 2143. Planet Earth was destroyed 131 years ago and now any inhabitants of Planet Earth are living on Mars. All inhabitants of Earth were relocated unless they didn't want to move. If they made the choice to stay behind, they were instantly killed when Earth blew up. During these 131 years since humans were relocated, the government and scientists have figured out how to continue human life on Mars. Because of this, every person is required to have a surgery on their fifteenth birthday, to make them more like an adult. This will change their looks slightly, and alter their brain chemistry. Everyone has the surgery, even if they disagree secretly and even if they don't want to. And before, Echo Hilton, no one has ever challenged it. And soon, life on Mars is about to change.
