Harriet Beecher Stowe and Hannah More Changed the World.
Well written and very informative. My wife read Uncle Tom's Cabin on her own. I started but never finished. It was not required reading at any school I attended. Any Mark Twain books should be read, Treasure Island, To Kill A Mocking Bird, Gulliver's Travels, and the Watson's go to Birmingham are the only ones that come to mind at this time; but there are plenty more out there.
