"This friendly, fun biography series focuses on the traits that made our heroes great--the traits that kids can aspire to in order to live heroically themselves. Each book tells the story of one of America's icons in a lively, conversational way that works well for the youngest nonfiction readers and that always includes the hero's childhood influences. At the back are an excellent timeline and photos. After escaping from slavery herself, Harriet Tubman risked her life and her freedom to help other enslaved people reach safety via the Underground Railroad. She is one of America's most important humanitarian and civil rights heroes."--Publisher marketing.
