‘The lorry is ready to take you to the train station,’ the soldier announced, and Martha clung to her little sister. ‘I want to stay with her,’ Martha said, voice shaking. ‘It is not possible. You belong in the Reich,’ the officer said. ‘And she does not.’

Poland, 1944 When twelve-year-old Martha and her little sister Johanna are snatched while out shopping for food and pushed into an army truck with a swastika on the door, they are heartbroken. Terrified they will never see their mother again, the little girls cling to each other as the truck full of stolen children rumbles through the countryside.

But worse is yet to come. When they arrive at their strange new home, tears streaming down their cheeks, Martha is sent into a separate room. As she is measured, her blonde hair and blue eyes exclaimed over, she doesn’t realise she has seen her sister for the last time. Later, as she sobs alone in the chilly dormitory, her only crumb of comfort is the memory of a kind German nurse who took a photo of the two sisters, and promised Martha she will do what she can to find Johanna.

Berlin, 2005 In her cosy sitting room, seventy-year-old Martha freezes. The woman on her television talking about lost children is someone she could never forget. Margarete Weiss is the nurse who took the photo of her and Johanna, the photo with the secret message on the back…

Martha has never been able to find her younger sister and has buried herself in work so as not to be haunted by the ghosts of her past. But, seeing Margarete’s blue eyes again, a shoot of hope takes root in her heart. Margarete may not have been able to prevent the sisters being separated during the war. But might she be able to help Martha find out what happened to Johanna now?

A beautiful and emotional read about finding hope in the darkest corners. Fans of The Midwife of Auschwitz, Before We Were Yours and The Orphan Train will lose themselves in this beautiful and heartbreaking book.
