Sixteen-year-old Bobby is the only human on a robot-inhabited planet. Aided by LINC, his cybernetic haywire task assistant, he must prove to the bots that the human race is worth restarting by passing his Programming, the training he receives to think and act in perfect precision-and without emotion. Failure will force him to upload his mind into the Tether, a robotic host, stripping him of his humanity and terminating his species' last chance for survival. As he repeatedly falls short of the bots' rigorous standards, he begins to question if the human race is even worth reviving. But when a beautiful girl named Jen crash-lands on his planet, she makes him question everything the bots have told him, including what it means to be human.
