Every year in Quill, thirteen-year-olds are sorted into categories: the strong, intelligent Wanteds who go to university, hardy Necessaries who take on menial tasks, and the artistic Unwanteds who are sent to their deaths.

In a nearly unprecedented verdict, thirteen-year-old twins Alex and Aaron are separated. Alex can barely keep it together as he’s led away from his Wanted brother to his own Unwanted fate.
