A novel in which the author claims to be telling the real and true account of their life. Usually of interest only when hyphenated by such things as a crack, gambling, or sex addiction, or any of several forms of abuse--although the more graphic (but not disturbingly graphic), the better. If you have had a dull life it is recommended that in true writerly fashion you make something up. Either that or develop a conceptual strategy to make it more interesting.
