In 1936, the Nazis are little more than brutish boors to fifteen-year-old Stephan Neuman, a budding playwright and the son of a wealthy and influential Jewish family in Vienna, Austria. Stephan’s best friend and companion is the brilliant Žofie-Helene, a Christian girl whose mother edits a progressive, anti-Nazi newspaper. But the two adolescents’ carefree innocence is shattered when Hitler’s forces advance.

There is hope in the darkness, though. Truus Wijsmuller, a childless Dutchwoman, risks her life to smuggle children out of Nazi-occupied lands to the nations that will take them. It is a mission that becomes even more dangerous as countries across Europe close their borders to the growing number of refugees desperate to escape after the Anschluss, Hitler’s annexation of Austria.

Tante Truus, as she is known, is determined to save as many children as she can. After Britain passes a measure to take in young refugees from the German Reich, she dares to approach Adolf Eichmann, the man who would later help devise the “Final Solution to the Jewish Question.” Truus then sets off in a race against time to lead hundreds of children on a perilous journey to freedom.
