What if the person you thought you knew best turns out to be someone you never knew at all? Andrea Cooper knows everything about her mother Laura. She's knows she's spent her whole life in the small town of Gullaway Island; she knows she's never had any more ambition than to live a quiet life as a pillar of the community; she knows she's never kept a secret in her life. But one day, a trip to the mall explodes into violence and Andrea suddenly sees a completely different side to Laura. Twenty-four hours later, Laura is in hospital, shot by an intruder who's spent thirty years trying to track her down. Now, Andrea must go on a desperate journey to follow the breadcrumbs of her mother's past. If she can't uncover the secrets hidden there, there may be no future for either of them.
