Every so often you will hear someone say something to the extent of, ugh, in every dystopian it always turns out that the lead character is possessed of whatever magical combination of luck, skill, secret power, and/or timing that leads to them being the perfect person to overthrow the system. Why can't we read a story about someone else?
Well, the short version is that fiction is about people who do things. I could write a story about Princess Leia's best friend who just you know, lived her life on Alderaan until one day her planet blew up and um, yeah, that is not a story. Now, there are exceptions to everything. And if I ever write a dystopian it probably would be about someone on the fringe. Partly because a lot of the time, I'm really fascinated with what happens after. What do the people who went to high school with Peeta and Katniss do now that their whole world has been upended? But again, it would need more to be a story. I say this as someone who loves reading romances, and enjoys World War II fiction a lot, but not every story lends itself to romance. And yes, I realize I have once again compared, "Star Wars", dystopian, and WWII fiction.
