The year 1944. "I have to go away, my darling. Please, be brave, stay alive, for me." Her mother’s voice breaks. The little girl tries to stop the forbidden tears from falling, as the train takes her mother, and she is left alone in the camp....

Berlin, six years later. When Hanni Winter shows her new husband the heartbreaking photos she captured during the war, his reaction is unexpected. His face white, Freddy can’t take his eyes off the photo of a young girl around four years old.

"That’s Renny," he whispers, "my sister, she was taken by the Nazis...."

Hanni remembers her perfectly–the child with the wide eyes and bitten lips, who wouldn’t let herself cry despite the chaos and cruelty all around them in the camp. Her heart had broken for the little girl as she took her picture, desperate to reveal the truth about the Nazis to the world. If that child is Renny, then they must try to find her. They must return to hell on Earth.

But when Hanni arrives at the black and white arch of the camp, she comes face to face with a man she fears more than any other. Can she find the strength to fight again, or will every hope for the future be lost forever?

A heart-wrenching novel about love and courage in the face of terrible odds. Fans of The Alice Network, The Nightingale, and The Tattooist of Auschwitz will need a box of tissues handy.
