Mary Rostad was only sixteen years old when Nazis conquered her home city of Brussels in 1940. She joined the resistance movement, serving in Belgium and later France, as a courier of underground documents. Adopting the code name “Squirrel,” she walked over one thousand miles in frigid temperatures, far away from her home and her family to report on the movement of German troops. This heroic story challenges us to consider how we would act if faced with adversity.
