In April 1940, as the Nazis march into Denmark, a rich girl named Sydney Brant marries a gifted Danish pianist, Laurus Moss. Almost at once, their views of the world and their marriage begin to diverge. When Laurus chooses to leave Sydney in the fall of 1941 to help build a Danish Resistance from London, Sydney is dismayed. By the time they are reunited four years later, Laurus's family and the reader have been through one of the most stirring stories of the war: Denmark's courageous grassroots rescue of virtually all 7,000 of the country's Jews. Meanwhile, in America, Sydney has led a group knitting for the war effort, and had a baby. In the decades to come, many people, especially their three grown children, will wonder whether these two very different people understand each other at all.
