When Mary Jo Clark died at age 90, she left behind a library that nobody knew existed. In the back of a desk drawer, and in a sealed carton, her children found seven desk calendars, chronicling the years1937 to 1943. On thousands of three by four inch pages, Mary Jo tells the story of her young adulthood. But it's also the story of her generation, which has been dubbed ' The Greatest Generation.' Raised in the Great Depression, they came of age just in time for World War II. It's a story of faith and family, of hard work and of a hunger for education and advancement; a story of wartime separations and tragedy, and a love story too.
