Number The Stars by Lois Lowry

The unforgettable Newbery Medal–winning novel from Lois Lowry. As the German troops begin their campaign to "relocate" all the Jews of Denmark, Annemarie Johansen’s family takes in Annemarie’s best friend, Ellen Rosen, and conceals her as part of the family.
Through the eyes of ten-year-old Annemarie, we watch as the Danish Resistance smuggles almost the entire Jewish population of Denmark, nearly seven thousand people, across the sea to Sweden. The heroism of an entire nation reminds us that there was pride and human decency in the world even during a time of terror and war.
A modern classic of historical fiction, Number the Stars has won generations of fans and continues to speak to today's readers. Jessica Grose wrote in a November 2022 New York Times essay entitled "This Perfect Mother-Daughter Read Holds a Powerful Lesson for Fighting Antisemitism": “Number the Stars is particularly relevant to our family, and to this moment."
