Every year the government would take two fifths of the new eighteen year olds and take them to the central hub. There they question them to find out their ideal world, subsequently sending them off to live their lives in the place which is determined to be perfect for them. Though there is one world which is not designed for the common people, but rather the violent criminals. It is world run by ruthless gangs and a world which contains no laws, other than do whatever you have to do to survive. Eighteen year old, Isaac, goes to the hub dreaming of a beautiful countryside world. But when he finds himself being sent to World 42 his life is turned upside down. He discovers friends, and uncovers conspiracies which will change the very nature of the earth.
