After the apocalypse, the earth's last outpost has been ruled for 700 years by an embodied AI, the Silver. Each person has a designated number and through merit on can "rise" to better one. 1,008 Tamar is a young woman who lives by thievery and aims to remain obscure, taking care never to earn a rise. Then she meets an agent of the Silver, Rafayel, a man who has been granted immortality. He means to use Tamar to his own ends, propelling her from the slums to the top echelon of society. There she will discover terrible secrets-one of which may destroy the last bastion of humanity.
