Chemical warfare has obliterated most of the world, including America, and the survivors have turned into feral beasts, save one colony, Antius, the last remnant of civilization. Seventeen-year-old Cori (aka Citizen 1206) only longs for wide open spaces and freedom. But Antius has no use for such things, just mindless drones to serve in a place with walls, fences, and laws. A lot of laws, which Cori constantly breaks. So she's spent years plotting her escape, which is the only thing that will save her from the colony's deranged leader, Nathan. She isn't looking to be a hero, and she certainly...

Consumed by guilt from a war she started, Cori faces the aftermath of her destruction. The Mercy colony is in shambles as infection spreads and Dylan struggles to find a cure before it's too late. Cori's love and loyalties are put to the test when he asks her for the unthinkable. Now faced with impossible decisions, Cori must risk her friends and everything she's ever cared about in order to put things right. She'll go to unimaginable lengths to save the innocent, no matter the cost.
