Nox is a 16 year old girl trapped in an organization built to raise "perfect people" with intentions of selling the best of them off to work for the rich. Being one of these chosen people is a highly esteemed achievement, and in order to produce individuals who are above the rest, the organization is filled with strict rules. Break them, and you'll be sent to the Outside, a barren wasteland where all who've been exiled there have allegedly died of hunger, thirst, or were killed by rogue "Outsiders". When a new rule pushes her limits too far, Nox is forced to make a choice: lose the person she cares about most, or be exiled to the Outside to fend for herself.
