Mason and Harper live in a trailer park in a corner of what was once a powerful city. They struggle to survive, and to hold on to their love, in a dystopian future where a caste system has arisen as pervasive as any in India, shackling citizens to their work and to their allotted living space. The only alternative is joining small survivalist colonies outside the system. Some are savage and brutal, others altruistic and resourceful. Acceptance to one has become a matter of life and death. Resistance has become the only way of stealing back hope.
