In the midst of World War II, everyone was doing their part. Some went to fight, some grew their own gardens, and some worked in factories. Margaret's dad chose to work in a factory. Her family moved from New York to Willow Run, Michigan so that her dad could build planes for our troops.
Margaret writes letters to her brother (who is in Europe, fighting) and to her German-American grandfather (who stayed behind in New York). Margaret's world is turned upside down when her family receives notice that big brother Eddie is missing in action. Margaret learns that life goes on, but you must always be brave and remain hopeful.
