If she succeeds in finding him, he’ll be charged with murder. If she fails, he won’t likely survive on his own. It's 2064.

Ana lives in the City, an experimental community that has had little contact with outsiders in decades. When her older brother Finn disappears on her 22nd birthday, a seemingly impossible event given the extensive monitoring in the City, she quits school, moves into her station wagon and embarks on an obsessive manhunt.

Unable to find him on her own, she’s forced to partner with Aaron, a detective with his own complicated history and agenda. Together they comb the dregs of the outside world, encountering both the horrors of lawless survivor communities and the unclaimed beauty of the old world.

As Ana comes closer to understanding her brother’s disappearance, she's forced to confront the truth about herself and her place in the City.
