Sarah Hoyt, whose books I have not read, has recently begun advocating for what she calls “human wave science fiction.” And I’m all for it.
Check out her manifesto, which is really all about good story-telling. I’m especially fond of her rule #2:
2. Your writing shouldn’t leave anyone feeling like they should scrub with pumice or commit suicide by swallowing stoats for the crime of being human, or like humans are a blight upon the Earth, or that the future is dark, dreary, evil and fraught with nastiness, because that’s all humans can do, and woe is us.
