'That was my punishment: to have left them - Mary-Pat, June, Pius and my little Rosie - and yet brought them with me in my heart, where I could never let them go.' Nearly thirty years after their mother's disappearance, the O'Connor children still bear the scars of her leaving. Mary-Pat pushes her own family further and further away. June quietly lives her own lie. Pius has shut himself off from the world, while Rosie has spent the past ten years denying who she is. When Rosie returns to the small town where they grew up to get married, she awakens old ghosts. As the siblings are forced to confront the reason their mother left all those years ago, they begin to realise that for things to be fixed, first they have to be broken. And for their mother, time has not erased the pain of leaving them. All That I Leave Behind is the story of a family torn apart by passion, and the conflict between love and duty.
