From the bestselling author of The Secret Midwife comes a story of selfless sacrifice, women’s bravery and the importance of keeping memories alive.

We’ll make sure they never forget. We’ll make sure that every recipe, every poem, every note is remembered, and never, ever forgotten. Even if it takes me a lifetime, I promise you that no one will forget…

Amsterdam, 1940: Schoolteacher Aletta knows the war will soon reach her and the Jewish children in her class. When her family hide an injured Allied airman in their home, they must how much will they risk when resistance could prove deadly?

Paris, 1940: Since her mother’s death, Chloe has dedicated herself to protecting her brothers. So when the SS accuses Claude of being in the Resistance, she sacrifices herself to save him.

Forced together in Ravensbrück concentration camp, Chloe, Aletta and her mother, Emma, forge an unbreakable bond. Surrounded by unimaginable cruelty, they mount their own kind of resistance—secretly teaching children and preserving fellow prisoners’ precious memories. In a place designed to strip away humanity, their friendship becomes an act of defiance, their determination to bear witness a lifeline of hope.

As the war rages on and whispers of a longed-for liberation grow, can their courage and sisterhood see them through to freedom? And if they survive, how can they ever be the same?

Based on true events, this is an inspiring testament to the power of friendship and the resilience of the human spirit.
