Author Azar Nafisi has written a love letter to literature and reading in Read Dangerously: The Subversive Power of Literature in Troubled Times. She does this in a series of letters to her late father who passed on in 2004. Nafisi says that reading can help us really live and also help us, and has helped her, survive challenging times. Nafisi told NPR's Scott Simon that literature's purpose is to let us experience new worlds: "to come out of yourself, and join the other."
