Conversation: Writer Barbara Kingsolver

"The Lacuna," a new novel by "Barbara Kingsolver":http://www.kingsolver.com/, is a sweep of history and a mix of the real and the imaginary: From the vibrant political and artistic Mexico of the 1930's -- including the historic figures muralist "Diego Rivera":http://www.pbs.org/newshour/bb/entertainment/july-dec99/rivera_7-15.html, his wife, artist Frida Kahlo, and the exiled Soviet leader Leon Trotsky -- to post World War II America, where optimism is mixed with fears of communism and the House Un-American Activities Committee. Kingsolver is also the author of the bestseller "The Poisonwood Bible." She joined me to discuss her new work.
