England, 1944. As I look around the childhood room I used to share with my twin brother, Ed, I realize just how much the war has taken from us already. Ed was never the same after he helped our father in the Dunkirk rescue. Clutching his call-up letter in my hands, I know that Ed has fled, leaving behind his family and all he has ever known. But I know that if Ed fails to accept his call-up then he will be found and imprisoned. I'm his sister, and I'll do whatever it takes to protect him. As I step into his overcoat and study myself in the mirror, I realize there might just be a way to save him, if only I can find the courage to do it. Arriving at the call up, I'm told that I'm to become a Bevin boy, one of the many men called to work in the mines and power the country through the war. I hesitate, unsure if I can really take on such difficult work whilst my friends become land girls and nurses. But my brother and my country need me, and in that moment, I vow to do whatever it takes. As I adapt to my new life, I meet a young man named Peter, and as we grow closer, I realize that I am slowly losing my heart to him. But I know the risks if the secret of who I really am is ever revealed. How much am I prepared to sacrifice for the ones I love the most? Perfect for fans of The Alice Network, The Nightingale, and Rhys Bowen, this completely gripping and heartbreaking story of love, courage, and a sister's sacrifice shines a light on the forgotten heroes of World War Two.
