Fifty years ago, one of the most influential books ever written hit the book stands. It was largely successful from the get-go, earning its author a Pulitzer less than a year after it was published.
Its message touched large swaths of the American public, reaching across demographics and geographic boundaries. It turns out it even reaches across the boundaries of time -- To Kill a Mockingbird is not just a classic, but it remains as popular among today's readers as it was 50 years ago. In fact, it has proven to be so successful that author Harper Lee has never written another book.
