10-year-old Annemarie Johannesen narrates this story (based on real events) set in Denmark during WWII. The Danish resistance arranged to transport many Jews to safety in Sweden after they found out that Jews were being sent to concentration camps by the Nazis.Annemarie is not Jewish, but her best friend, Ellen, is. Annemarie's family helps smuggle Ellen and her parents, along with several other Jewish families, out of the country. Lowry manages to give the reader a sense of the horror of the Holocaust without going into graphic detail.
