When we first start writing fiction, we do it because it’s fun, because we enjoy it, because it allows us to create and exist in worlds and amongst people that we are unlikely to ever encounter in our real lives. Sometimes that includes worlds and people we would never want to meet in real life.
It’s often only when others start reading our fiction that analysis begins and labels are bandied about. Genres are so varied and specific these days that there is almost always one to suit anything that is being written. And if there isn’t, we create new ones.
Beyond genre, though, there are three categories into which everyone’s writing will fall. They are categories that when we are writing we don’t think much about. But our writing will inevitably fall into one or snugly somewhere between two. Those three categories are realism, escapism and absurdism.
