Make a great movie in the "R" category. Length of number of pages does not lend itself to reading at one sitting, but requires at least two or three. It uses a first person narrative form and uses the "flash back" method to fill in gaps that seem to be missing in the story-line. Sexual content is fairly graphic (even with flash back narrative) and adult enough that it would probably, if made into a movie, require teens approaching adulthood to be allowed in Of course, the censorship would soften what would otherwise adult language.
