What is a normal life? Look at Nina Oberon. Everything is ok and nothing beyond the normal. As all girls of her age, on her birthday, when she was 16 she had received a Governing Council-ordered. Those three letters will be branded on her wrist, announcing to all the world - even the most predatory of men - that she is ready for sex. Considered easy prey by some, portrayed by the Media as sluts who ask for attacks, becoming a "sex-teen" is Nina's worst fear. That is, until right before her birthday, when Nina's mom is brutally attacked. With her dying breaths, she reveals to Nina a shocking truth about her past - one that destroys everything Nina thought she knew. Now, alone but for her sister, Nina must try to discover who she really is, all the while staying one step ahead of her mother's killer.
