Book 3 of the Shadow Children series
by Margaret Peterson Maddix (5th+)
Nina Idi used to be a student at the Harlow School for Girls, which was connected by a forest to the Hendricks School for Boys. She was one of the girls that used to sneak into the forest at night to meet boys of her kind, third children. But one of the boys, Jason, whom she loved, has betrayed her and now she finds herself in a Population prison. She finds herself in a cell with two brothers, Matthias and Percy and their sister, Alia. She has been given two options--get the siblings to admit to being third children or be put to death. Can she turn around and betray the children as she was betrayed? Or will she choose to be put to death? Is it possible there is another option not yet found? Find out by reading Among the Betrayed, the third book in the Shadow Children series by Margaret Peterson Haddix.
