Special to CNN
Sarah Palin appears on Oprah on Monday to mark the launch of her book, "Going Rogue." She'll follow up with an extensive interview with Barbara Walters, a multicity book tour and appearances on the Fox News Channel and talk radio.

Anderson Cooper goes beyond the headlines to tell stories from many points of view, so you can make up your own mind about the news. Tune in weeknights at 8 and 10 ET on CNN.
