Wise Blood by Flannery O'ConnorRead about another entry on the list.
It's hard to decide on the worst person in O'Connor's blackly comic 1952 tale of apostates, con artists, and aggressively stolen gorilla suits. Asa? Mrs. Flood? Hoover Shoats? It could be Hazel Motes himself, so incensed by the irrationality of faith that he goes utterly mad.
Wise Blood is among Jamie Kornegay's ten best Southern Gothic books.
