A ground-breaking study of Flannery O'Connor and her place in American culture, A Wreck on the Road to Damascus weaves together high art and popular culture in a way that makes literary criticism exciting. Drawing on a wide range of sources, Brian Abel Ragen shows not just the depth of O'Connor's religious vision, but also the ferocity of her attack on the literary tradition that at once denied original sin—her favorite doctrine—and shoved women to the margins of American culture. His work will change the way readers think about Flannery O'Connor, automobiles, original sin, and American culture.
I read a couple of dozen interpretations etc. of Flannery O'Connor's Wise Blood. And this was the best of the bunch. However does not explain the ending. Have to read a couple of articles by Ralph Wood for that.
