On a car journey to a family wedding, Garance reflects on how adult life, with its disappointments and responsibilities, has not always gone to plan for herself or her three siblings. But just around the corner lies the chance for them to revisit their younger, carefree selves in a delightfully unplanned escapade. In this exquisitely told story, Anna Gavalda explores the themes of time passing and the highs and lows of family life with characteristic wit, warmth and brilliant characterisation.
