Colson Whitehead's "Underground Railroad"

One of this year's big novels is Colson Whitehead's sweeping historical novel, "The Underground Railroad." It's an unflinching look at the experience of slavery, inspired by the classic slave narratives. And being a sci-fi geek, Whitehead also weaves in bits of fantasy, creating an alternative history that features an actual underground railroad and other historical oddities. In this extended podcast interview, Whitehead tells Steve Paulson that he wasn't going to stick to the facts, but he did stick to the truth.
