Alex Gordons lives under the supervision of the guards from the Organization. She has lived at the Organization's compound for what feels like decades. She doesn't remember much of her family, and doesn't know why she was taken to the Organization. Hundreds of other kids are just like her. The Organization has Alex and every other kid divided into four sectors; the blues who are the brains, the greens who are the genius builders, the reds who are the fighters, and finally the blacks.
Order and discipline are very important at the compound, and the sectors are to keep to themselves and those who live at the compound are to follow the sector heirachy- with the blacks at the very top. Things stay that way until Alex outplays a black, and discovers that things aren't what they seem.
Alex doesn't know why she is here. She only knows what they tell her.
