Harriet Beecher Stowe's novel Uncle Tom's Cabin was a book that worked to expose northerners to the evils of slavery. Harriet Beecher Stowe sought to write a book that would expose the horrors of slavery and to expose the injustices that were taking place in the American South that Northerners might not have been fully informed about at the time. The book was certainly not hailed as a marvelous work in the South and was instead decried and bashed because it sought to expose the practices employed in the South's use of slave labor.
