Grace is about to turn ninety. She doesn't want parties or presents or fuss. She just wants to heal the family rift that's been breaking her heart for decades. But to do that she must find her daughter Alys - the only person who can help to put things right. And when she finds her - if she does - she risks betraying granddaughter Elin. Who is far less forgiving of the past, with its hurts and secrets and lies. Meanwhile Grace's great-grand-daughter Beca is oblivious to all these worries, too busy navigating the highs and lows of teenage life and keeping secrets of her own. All families have their problems. And most of them get resolved. But Grace's problem is thirty years old. And she doesn't have time on her side. So is it too late for her to make peace? Or is reconciliation still within reach?
