Gray Rinehart writes science fiction and fantasy stories, nonfiction, songs ... and other things. He is the only person to have commanded an Air Force satellite tracking station, written speeches for Presidential appointees, originated a poetic form, and had music on The Dr. Demento Show. He is currently a contributing editor (the "Slushmaster General") for Baen Books.

Gray is the author of the lunar colonization novel Walking on the Sea of Clouds, and his short fiction has appeared in Analog Science Fiction & Fact, Asimov's Science Fiction, Orson Scott Card's Intergalactic Medicine Show, and multiple anthologies. As a singer/songwriter, he has two albums of mostly science-fiction-and-fantasy-inspired music.

During his unusual USAF career, Gray fought rocket propellant fires, refurbished space launch facilities, "flew" Milstar satellites, drove trucks, encrypted nuclear command and control orders, commanded the largest remote tracking station in the Air Force Satellite Control Network, and did other interesting things. His alter ego is the Gray Man, one of several famed ghosts of South Carolina's Grand Strand, and his web site is graymanwrites.com.
