Do Richard Matheson and Morgan Llywelyn write different genres of books than eachother?
Richard Matheson Richard Burton Matheson (February 20, 1926 – June 23, 2013) was an American author and screenwriter, primarily in the fantasy, horror, and science fiction genres. He is best known as the author of "I Am Legend", a 1954 science fiction horror vampire novel that has been adapted for the screen four times, as well as the movie "Somewhere In Time" for which Matheson wrote the screenplay, based on his novel "Bid Time Return". Matheson also wrote 16 television episodes of "The Twilight Zone" for Rod Serling, including "Nightmare at 20,000 Feet" and "Steel".
Ecofiction Ecofiction (also "eco-fiction" or "eco fiction") is the branch of literature that encompasses nature-oriented (non-human) or environment-oriented (human impacts on nature) works of fiction. While this super genre's roots are seen in classic, pastoral, magical realism, animal metamorphoses, science fiction, and other genres, the term ecofiction did not become popular until the 1970s when various environmental movements created the platform for an explosion of environmental and nature literature, which also inspired ecocritism, the study of, among other ideas, humanity's connection with nature in literature. By this time, natural histories of ecology were modernizing, and literature followed. Environmentalists had claimed that the human relationship with the ecosystem often went unremarked in earlier literature.
