Meggie Dillon's life has been turned upside down by World War II. Meggie's father has announced that they must help the war effort and move to Willow Run, Michigan, where he'll work nights in a factory building important war planes that will help fight the enemy in Europe. Willow Run will be the greatest adventure ever, Meggie thinks. There she meets Patches and Harlan, other kids like her from far-off places whose parents have come here to do their part in the war. And there she faces questions about courage, and what it takes to go into battle, like Eddie, and to keep hope alive on the home front.
