After a series of natural disasters sends America into chaos, society is divided into two factions. The privileged elite are ushered into one of the United Seven Cities of America, where modern life continues. The rest remain outside the impenetrable modular walls, sifting through the wreckage of the old world trying to survive.

Dia Demarco is just old enough to remember what civilized society was like, but still young enough to think she can make a difference. She didn’t ask for this life. It was thrust upon her by the tragic events of a world gone very wrong. But that’s not going to stop her from kicking ass with no intention of taking names.

Breaking into the secure city, alone, is not an advisable move. But she’s the only one who can save her little brother, Ray. He was bootstrapped into the city with a host family, but refusal to follow his designated life path has put him in danger of a fate worse than death.

What Dia discovers is a much darker secret brewing inside the city walls.
