^^^ Me again. M Harold Page. The writer with the swords and some books in print, rather than the one with the cats and a metric tonne of books in print (plus enough rockets that we really should get him that Tracy Island in which to keep them).
Did I say "swords"?
Right now it's actually blasters because I'm wearing my Space Opera hat.
Yes, despite all my books to date featuring many, many swordfights, I wrote a Space Opera. It's called "The Wreck of the Marissa (The Eternal Dome of the Unknowable #1)".
And yes, as you might guess from its title, it's at the other end of the spectrum from the transhuman wibbletech extrapolative futures that Charlie likes to explore. It's also not Military SF. Though there's fighting - the protagonist is a retired mercenary turned archaeologist - it's small scale stuff and the focus isn't on the regular army.
But what subgenre is it?
The same subgenre as EC Tubb's Dumarest books - hero wanders the galaxy in search of Earth - or Moon's Vatta's War - hero trades across the galaxy while coming to her family's rescue - or Firefly - oddball crew trade between worlds - or, of course, the venerable Traveller Roleplaying Game - I've been reviewing the new Mongoose Traveller over on Black Gate (*).
It's partly defined by vibe; hardboiled adventure in an imperfectly distributed future where there are more planets like Tatooine than Coruscant. However, it's also defined by protagonist(s) and scope; independent operators struggling to make a go of it in a hostile human universe with the antagonists capped at corporation or "house" level, with no Dark Lord, and no saving the galaxy.
You know exactly what I mean. It's the subgenre that that bears the same relation to Space Opera that Sword & Sorcery bears to Heroic Fantasy.
But it doesn't have a name! And though I'm half a century late to the game, I think we should call it "Star Punk".
