Eric C. Holtgrefe

From an early age, Eric has always been fascinated by stories about outer space. By education, he is a computer scientist. For over twenty years he was a systems engineer. He has traveled and worked all over the world in various industries; including time flying satellites for NASA. He values the titles of: Christian, Father, Husband, Engineer, Medievalist, Historian, and Homesteader the most. When he isn’t writing, Eric is chicken wrangling, herding mostly sentient schnauzers, punching variform cattle, bending stable diffusion to his will, and directing the drones on his eleven-acre farm in the Ozarks of Missouri.
