When the Nazis invaded Denmark on Tuesday, April 9, 1940, the people of this tiny country to the north of Germany awoke to a devastating surprise. The government of Denmark surrendered quietly, and the Danes were ordered to go about their daily lives as if nothing had changed. But everything had changed.

Award-winning author Deborah Hopkinson traces the stories of the heroic young men and women who would not stand by as their country was occupied by a dangerous enemy. Rather, they fought back. Some were spies, passing tactical information to the British; some were saboteurs, who aimed to hamper and impede Nazi operations in Denmark; and 95% of the Jewish population of Denmark were survivors, rescued by their fellow countrymen, who had the courage and conscience that drove them to act.
