Andrea Cooper knows everything about her mother, Laura. She knows she's spent her whole life in the small beachside town of Gullaway Island; she knows she's never wanted anything more than to live a quiet life as a pillar of the community; she knows she's never kept a secret in her life. Because we all know our mothers, don't we? But all that changes when a trip to the mall explodes into violence and Andrea suddenly sees a completely different side to Laura. Because it turns out that before Laura was Laura, she was someone different. For nearly thirty years, she's been hiding from her previous identity, lying low in the hope that no one will ever find her. But now that she's been exposed, nothing will ever be the same again. Twenty-four hours later, Laura is in the hospital, shot by an intruder who's spent years tracking her down, and Andrea finds herself desperately following 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.
