It is the summer of 1940, and all of England fears an invasion by Hitler’s army. When Norah learns that she and her brother Gavin are being sent to Canada, she’s not sure what to expect; she only knows that she doesn’t want to leave her home, her family, or her friends. The rich woman who takes them in prefers Gavin to her, the children at school taunt her—and, as the news from England becomes worse, she longs for home. But as Norah begins to make friends, she discovers a surprising responsibility that might help her accept her new country—and her new situation. Will Norah and Gavin be able to find their way through the shadows of war, even as the sky is falling?
