This powerful, meticulously researched novel is a moving tale of one girl's struggle against a world in turmoil. In 1930s Berlin, choked by the tightening of Hitler's fist, the Klein family is gradually losing everything that is precious to them. Their fifteen-year-old daughter, Rosa, slips out of Germany on a Kindertransport train to begin a new life in England. Charged with the task of securing a safe passage for her family, she vows that she will not rest until they are safe. But as war breaks out and she loses contact with her parents, Rosa finds herself wondering if there are some vows that can't be kept. A sweeping tale of love and loss, with the poignant story of the Kindertransport at its heart, this is an exceptional accomplishment from one of Britain's bravest and most-vibrant young writers.
