Parents can have their childrens' genes sequenced for free when their children turn thirteen. A young fifteen-year-old freshmen by the name of June is ninety percent predisposed to borderline personality disorder. She is hopelessly in love with a mysterious boy named Mercury who, if rumors around the school were to be believed, had abusive parents, and was therefore a likely candidate for the psychopath gene. June shows very few signs of the mental disorder at first, but, everything changes when her mother one day changes and loses interest in her daughter. June feels her life spiraling out of control without her mother's affection, and seeks attention from a boy named Justin instead.
