The Rough Guide to Space Opera: C. M. Gilbert - Blue Tyson
C. M. Gilbert is a curiosity, the author of one novel that I am aware of. It was actually marketed as Sword and Sorcery but isn't. The 1981 novel The Ozine Conquest has a disgruntled steel-handed soldier getting involved with an ancient alien race and a conflict over a space station and the alien transport technology. Complete with Star Traders and a barbarian priestess. On her planet comes the low tech science fantasy bit for a time.
