Thirteen-year-old Maria Mitchell, known to all as Ria, and her friend Lydia have been assigned to write a report on a hero or heroine of the Great War (World War One) for a school project. Instead of picking some well known figure, the two friends decide to search for a forgotten or unknown hero or heroine. When asked to help, Emma Mitchell, Ria’s mom, brings out old letters she and a cousin wrote during the war. The girls are sure the letters hold the key to their success of finding a forgotten hero. But will they? Is that all that these letters bring to light? Join Ria and Lydia, Mrs. Mitchell, an old neighbor called Corporal, and others as they re-live the years of home life during the war.
