Among the betrayed

In the beginning of this chapter we meet the main character Nina. Nina is a third child. This is a big problem because in this society three children aren't allowed. In many cases the kids are killed if found. In this case Nina did not get killed because she's hiding in secret until some one "rated" on her. For years Nina thought her friends were trust worthy but one has told on her. Before she is killed the police give her a chance to live, but she has to turn in other third born children first.
