Andrea knows everything about her mother, Laura. She knows she's spent her whole life in the small beachside town of Belle Isle; 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 completely different.
