Bernice was a girl who did right by her blended family, she got good grades, she washed the dishes every now and then, she spent time with her stepsister--Prosepheny. After a fatal plane crash, Bernice wakes up in a hospital with her sister dead and her mother rejecting her as a stranger. Somehow, Bernice isn't Bernice; She's become a stranger to herself, Kylie Hanson. Cast off as a stranger, Kylie (or Bernice) finds a slip of paper in her pocket that tells her that her new life is permanent, she's immortal until she takes the life of another. Immune to sickness and death, Bernice lives a lonely life--until she meets the boy who both frees her and tears her world apart.
