Michael D. Cooper is an author about whom relatively little public information is currently available. He is known for a single work, The Runaway Asteroid. Because the available records contain no reliable information about his life, nationality, education, or writing career, it is not possible to say more about his personal background here. On the basis of the existing information, Cooper's writing is associated with science fiction; the word "asteroid" in the title suggests a story involving space adventure or a celestial crisis, a kind of subject that often falls within popular science fiction or science fiction for younger readers. With only one work to go on, it is difficult to judge his overall style or the development of his writing, and it cannot be confirmed whether he continued to publish or had a noticeable influence on a particular readership. What can be stated is that, as the author of a single work, Cooper is currently known to readers mainly through this novel; a clearer picture of his writing and literary position will emerge only as more bibliographic information and public records become available.
