Kenneth C. Davis is a fantastic source of knowledge, whether it’s in the for of his “Don’t Know Much About” series, that takes on History, the Bible, the Presidents, etc. Well, he’s out with his new one, In the Shadow of Liberty: The Hidden History of Slavery, Four Presidents, and Five Black Lives, and it’s just as rich of a read as all his other takes, giving the true stories and facts of one of the darkest periods in our short history. Take a listen.
