I used to teach The Narrative of the Life of Frederick Douglass to my high school English classes. That book (which is free as an e-book on Amazon) is a passionate, poignant account of how he taught himself to read and write, and how that changed his life. When he lived, it was against the law for slaves to be taught how to read.
Being literate empowers people, especially now with the Internet and e-books available through cell phones. Having girls and women able to access this wealth of information must be incredibly destabilizing for cultures built around their subjugation. But it will happen. Girls will learn to read. I'd love to be alive a hundred years from now, and see the social changes this will drive.
