The year of her 50th birthday, Mary Moody ran away from home, family and work for six months to live in a remote French village. Her book about these experiences, Au Revoir, struck a chord with tens of thousands of readers across Australia. Yet those experiences were to mark a beginning rather than an end.

To her surprise, Mary found herself grappling with the intense emotion of an affair, and its consequences on her marriage and family. Amid this turmoil, Mary also rediscovered a sister not seen by the family for nearly 50 years.
