What is the theme in No Ordinary Time by Doris Kearns Goodwin?

Although Goodwin writes many pages about the battles and their strategies, her focus is on the American home front during World War II. She writes about the changes in the average American's life during that time. Women went to work in defense factories, making them more financially independent. For the first time, their work outside the home was valued and needed. Americans experimented with the first daycare centers.
