Bess is hoping to show everyone just how happy her recent marriage is, but behind all the party-planning the cracks are beginning to show. Why is joining a family so difficult? Jojo, Bess's stepdaughter, has a point to make. Bess is not her mother, and she won't replace the one she's been missing every day for the last two years. And will she ever get the chance to become a mum herself? Cousin Cari is a fierce career-woman who isn't unnerved by anything - apart from facing the man who left her at the altar, and he's on the guestlist. Her job has been a safe place to hide ever since - but is it time to let love into her life again? Thanks to laughter, tears and one surprise appearance, the Brannigans might just discover the secrets of a happy marriage. But will they find out before it's too late?
