In a world decimated by climate change, Emergent Biotechnology manufactures clones, called models - used as slaves to prop up a declining population. A woman's decisions determine an escaped model's fate and the fate of all model-kind. After her mother dies at the hands of her human-supremacist father, Harper learns that her mother was more than she seemed to be. When her mother's lover, an escapee, arrives at her door hunted and suffering from dehydration in the Texas heat, her opportunity for answers has a time limit. With another's future in her hands, Harper must fight through her emotions to help him find the refuge he seeks while being pursued by bounty-hunters, human extremists, and the limitless resources of the most prominent corporation in the modeling industry. Every day, the largest bounty in modeling history gets even larger.
