ⓘ About Thomas DePrima

Thomas Deprima is an American indie author, best known for his ‘Galaxy Unknown’ crime-drama series. He’s one of the most popular sci-fi author on the globe, despite having taken the indie route. In an interview, Deprima describes himself as a voracious reader, a habit he carried with him since childhood. He recalls picking up old paperbacks and thrift stores and yard sales for a nickel, and depleting an armload of them in just a week. He always felt like writing was his calling. But it was until 1997 that he decided to give it a professional shot. His first book was uploaded at a free fiction site, a site that allowed readers to critique other people’s stories as some form of payment for reading them.
