Christmas Eve, 2019. Ninety-four-year-old Molly lies in her hospital bed. A stroke and a fall may have broken her body – but her mind is alive with memories. London, 1940s. Molly is a bright young woman, determined to help the war effort and keep her head up despite it all. Life becomes brighter when she meets and falls in love with a man who makes her forget everything with one dance. But then war forces her to make an unforgettable sacrifice and when she’s brought to her knees by a daring undercover mission with the French Resistance, only her sister knows the secret weighing heavily on Molly’s heart. Now, lying in her hospital bed, Molly can’t escape the memories of what she lost all those years ago. But she is not as alone as she thinks. Will she be able to find peace – and finally understand that what seemed to be an ordinary life was anything but?
