Vivid and achingly real, Sally Nicholls's latest historical romance explores the fallout from an unexpected pregnancy during the First World War. It's Christmastime, 1919. Three years before, seventeen-year-old Margot Allan, a respectable vicar's daughter, fell passionately in love. But she lost her fiancé, Harry, to the Great War. In turn, she gained a desperate secret, one with the power to ruin her life and her family's reputation, a secret she guards at all costs. Now Margot's family is gathering at the vicarage for the first time since the War ended. And Harry, it turns out, isn't dead. He's alive and well, and looking for answers. Can their love survive the truth? Based on the author's family history, this evocative and stirring exploration of the human and emotional side of war is young-adult historical fiction at its finest, written with the immediacy and understanding of the complexities of the human heart that are the hallmark of the author's work.
