As of my last knowledge update in April 2023, there is no widely recognized author named Dianna Roman that stands out in literature, publishing, or online authorship. It is possible that Dianna Roman could be an emerging writer, a self-published author, or someone who has not yet gained significant notoriety in the literary world. Alternatively, the name might refer to a professional in a different field or a person with a modest online presence through blogs or articles without having published traditional books. If Dianna Roman is an up-and-coming author or has recently gained recognition, I would not have the most current information on her. You might consider searching for her on platforms that host independent or self-published works, such as Amazon’s Kindle Direct Publishing, Goodreads, or other social media sites where writers share their work and profiles.
