Anna lives with Oliver Robinson and their 3-year-old son, Charlie. They met when she worked as a waitress at his restaurant; he had recently separated and she was a shoulder to cry on, and friendship soon turned to love. Now she juggles motherhood with part-time work and couldn't be happier. But Oliver never divorced his first wife, Eve, who insists on making herself part of their lives. Anna understands that Oliver needs to support his two teenage children, but why should they keep Eve, too? The situation looks set to grumble on indefinitely unless someone or something shakes it up. And something does: Oliver is killed in a car crash, leaving both women shattered. How will they react to this appalling tragedy? Will it drive them further apart, or force them to cut their losses and pull together for the sake of their children and their futures?
