Ten years ago, Rachael West chose not to move to Sydney with high-school sweetheart Matthew. Instead she stayed on the family farm, caring for her seriously ill mother and letting go of her dreams. Now, Matthew is marrying someone else. And Rachael is invited to the wedding, a lavish affair in Paris, courtesy of the family of Matthew's fiancee - a once-in-a-lifetime celebration at someone else's expense in Europe's most romantic city. She is utterly unprepared for what the week brings. Friendships will be upended, secrets will be revealed - and on the eve of the wedding, Rachael is faced with an impossible dilemma: should she give up on the promise of love, or destroy another woman's life for a chance at happiness?
