For three years Olivia Penn has awaited a letter concerning her fiancé's whereabouts. Just when hope seems lost, the letter arrives. Nathan is alive, but he is being held in Japan as a war prisoner. Now only three things stand between Olivia and her beloved, half a continent, a stretch of ocean, and the world's second Great War. Olivia is determined to find and rescue Nathan-whatever the cost. She will not fail him, even if that means she must desert her post as a nurse, leave her few friends, and make the trek from Germany to Japan in the middle of a war zone-and she will do it alone. But when she leaves her unit's camp, doubt creeps in, little by little. And then she finds the wounded soldier. He is alone, but if she helps him, she might never reach Japan and Nathan. It is then she is faced with a terrifying decision between what is right, and what is impossible.
