Calyx hates the Immune. They are entitled, wealthy, white-collar gangsters who run the city of Genesis. They flaunt their immunity to disease and environmental hazards that nearly destroyed the human race while everyone else lives in masks and sterilized buildings. Calyx has avoided the Immune her entire life, but one night out with a friend takes a turn for the worse and brings her face to face with a whole pack of them. It’s a matter of do what she’s told or die but her abrasive, moody personality doesn’t help the situation.
