Author Kameron Hurley, in an essay for Uncanny Magazine:
I found the “I don’t know how to market this” thing to be a mind-boggling excuse, because I’d written the book I wanted to read. And if I wanted to read it, surely there were other people out there who wanted to read it too. What I would slowly come to realize over the years is that the people like me, who like the types of books I write – the wild, weird, punching and magic and genderbending books – were not the types of people who publishers were used to selling to. They had an Ideal Consumer in mind, and that Ideal Consumer seemed to be scared of women outside of prescribed roles, queer people who aren’t just sidekicks, and any setting weirder than something from Tolkien. Clearly, you know, the world is FULL of people who actually DO love to read books about and including all of those people and things.
This is a must-read for writers, and people interested in book publishing.
