Holly never thought she'd move back to her home town, but then something terrible happened. She doesn't know if she can recover. But she knows she can never tell another soul. People say her neighbour, David, is 'different'. He doesn't go out much, and never after dark. But in David, Holly finds just what she needs: a friend. Someone who's always there. No one knows Holly's secret, or where she lives. She has left the past behind. She is sure of it. So why does she feel as though she's in terrible danger?
