Speculative fiction is an umbrella genre that includes any fiction with supernatural, fantastical, or futuristic elements (see the Wikipedia entry). Science fiction and fantasy were often lumped in the past as "SF/F", but there were popular subgenres like dark fantasy and horror that fell within that sphere, as well. Lately, with the explosion of online book publishing, many signficant subgenres have grown more popular under varying names: urban fantasy, dystopian, steampunk, cyberpunk, post-apocalyptic, superhero, paranormal, alternate history, time travel, etc.
"Speculative fiction" (or "spec fic") is how you include all these genres in one phrase.
You might be wondering why I created an entire website just to explain this. Wasn't the Wikipedia entry enough?
Yes and no. I'm a passionate fan of speculative fiction, and I was tired of listing all my favorite subgenres and trying to explain what I liked. I wished there was a single, simple term I could use.
Spec fic is that term, but not enough people recognize it yet. You can help spread the word!
Spec fic isn't just for nerds. Speculative fiction used to be primarily identified with geeks who dressed up as Klingons for opening night at the theater. But not anymore.
The Lord of the Rings, Narnia, superheroes (Iron Man, Captain America, The Avengers, Superman, Batman, Supergirl, Arrow, etc), space opera and sci-fi (Star Wars, Star Trek, Doctor Who, Battlestar Galactica, Stargate, Interstellar, The Martian, etc), fairy tale and fantasy (Once Upon a Time, Grimm, Cinderella, Malificent, Into the Woods, etc), dystopian young adult (The Hunger Games, Divergent, Jupiter Ascending, Maze Runner, etc), the list goes on!
Speculative fiction is entering its golden age, so let's keep it trending. Share the graphics, wear your badges proudly, and help me enlighten the world about this handy umbrella term for all these wonderful stories. Spekkies unite!
