The Difference Between Science Fiction and Space Opera
Most readers don't really care what labels publishers or book sellers give to the books they enjoy, they are just interested in the books. But sometimes, those labels, or categories, interfere with finding just what a reader might be looking for.
I think mainstream science fiction and its sub-genres, science fiction romance and space opera, fall into that category.
Quite often, when someone finds out I write science fiction, they look slightly deer-in-the-headlights, and apologetically tell me they don't like that kind of book, and they'll look for my historicals instead. I don't mind that (really! There are some genres I don't love that much, too :)) but if I ask them if they enjoy movies like Star Wars, Star Trek, Serenity, or Guardians of the Galaxy, and they say they love them, then I tell them it's safe to give my books a go, because those movies are space operas, and that's what I write.
The difference between mainstream science fiction and the space opera and science fiction romance sub-genres is in the science.
Science fiction is supposed to be science-based, and that puts a lot of people off. Even if they are interested in science, some science fiction novels, especially what's called hard science fiction, has the reputation of being about too much detail. How big is the gun, what cool science has gone into the space ship, and so on. Science is almost a main character in the story, with a side-kick of technology and cool toys. If that's not your idea of a relaxing read, you'll probably avoid it.
The sub-genres of science fiction--space opera and science fiction romance—are about the characters and about the plot, with the science a minor thread. To understand what space opera is, just think of Star Wars and you'll know immediately, because Star Wars is a definitive example of the sub-genre. The world and its rules aren't explained, and there is no expectation that it will hold up to any kind of scientific scrutiny. Sometimes, though, the ideas that appear in space opera can in fact be prescient, like Edgar Rice Burroughs' space elevator, for example.
When I write my science fiction romance / space operas, I like to get at least the basic science right. The way gravity works, for example. :) And I do actively try to use known scientific concepts. I've watched How to Build a Planet and Brian Cox with the best of them, and my work is more accurate for it. I'm not a scientist, and I don't pretend to be one, and biology is more my field of interest than physics, but that said, some of the classic hard science fiction novels have subsequently had their science proven wrong, and new and wonderful things are being discovered in space all the time, so I'm actually not that worried about what I make up. Readers of space opera are looking for a fun, action-packed read, not an explanation about how the technology behind faster-than-light travel works. Which suits me fine!
If you listen to astrophysicists, a lot of what they say seems so outlandish, I don't think what I make up is really that much more outrageous :). Space opera is about the story, about the characters, and about the excitement and adventure. If you like those things, and haven't given space opera or science fiction romance a try, you are really in for a treat. Aside from my Class 5 series, there are hundreds of amazing books out there for you to find.
A group of science fiction romance / space opera authors got together, and we created the Portals Project, a set of volumes containing the first chapters of ten science fiction romance books per volume. They're a great way to find science fiction romance novels, and they're free. The first chapter of my SFR novel DARK HORSE, the first book in my Class 5 series, is in Portals: Volume 3, and you can download it for free at most major online book sellers.
We're celebrating today because the third and final book in my Class 5 series, DARK MINDS, was released today, and I had as much fun writing it as I did the other two. It has all the classic elements of space opera: romance, action, and intrigue.
With space opera, the only limit is your imagination. If you haven't given it a go, you're depriving yourself ;).
