In the city of Nomolos, where people have no names, a girl finds out why her world is what it is. Why nobody has names. Why they are all branded on their arms with a number. Why no one remembers anything about themselves, their past and how they got here in the first place. Why the government is so overprotective and secretive about everything. Why no one can leave or enter the city. All she knows is that her arm is branded with a number 6; one of the five missing numbers in her society.
