Wright Marion Morris was an American novelist, photographer, and essayist. He is known for his portrayals of the people and artifacts of the Great Plains in words and pictures, as well as for experimenting with narrative forms. Morris won the National Book Award for The Field of Vision in 1956. His final novel, Plains Song won the American Book Award in 1981.
I'm not going to give a long review of Wright Morris's About Fiction, but I'll only say this: If this were the first book you read by Morris, writing about how an author is called to write true-to-life, it wouldn't be a bad start. But I'd recommend The Territory Ahead over this, which encompasses a lot of Morris's themes here and more. The guy is great, and he's changed the way I look at literature.
