Her sister's boyfriend. Her worst nightmare. Ruby can't help but worry for her fragile younger sister, Sophie, who is still wracked with guilt over their mother's death. Still, she's glad that Sophie's boyfriend, Ewan, is supporting her. He's been her rock, not only taking care of her, but her two little kids, too. So what if he doesn't like talking about his past? When news of a woman's death spreads through their town like wildfire, Ruby doesn't want to suspect Ewan of foul play. But she knows that he was in the area of the murder at the time police say it happened. She knows because she was there too. That night, Ewan kissed her while walking her home - a fact that he desperately wants to hide. Ruby thought that the kiss was just a stupid mistake, but soon she can't help wondering if the man living in her sister's home is really who he says he is. As she digs, she quickly discovers how little she knows: about what her sister is hiding; about the secrets she's also willing to keep; and about what really happened to their mother on the day that she died.
