Among the Betrayed is a 2002 novel by Margaret Peterson Haddix, about a time in which drastic measures have been taken to quell overpopulation. It is the third of seven novels in the Shadow Children series. Unlike the first, it is not told from the viewpoint of Luke Garner, but instead from that of Nina Idi, the shadow child who was arrested with Jason Barstow at the end of Among the Impostors. Unlike Jason, who was a member of the Population Police, Nina is another third child who became Jason's pawn. The Spanish Version is called Entre the Betrayed.
