FICTIONS can be based on short stories, novels, plays, poetry, fairy tales, fables, fantasy and historical fiction. The common thread within fictional genres is the fact that the pieces are contrived largely from the author's mind and not based on actual facts. And a narrative account of a real event or person's life falls under the category of NON FICTION. Authors use expository writing to inform readers on a specific subject. Nonfiction persuasive essays are designed to present opposing viewpoints while swaying the reader one way or the other.
