Dunno what genre fiction is really, but a quick search tells me it's popular or bestsellers? Which is kind of funny because that's what Hemmingway would have been back in the day - really to me the opposite of academic style. Short sentences, no fancy words, no extraneous waffle just to show you how clever he is. It's kind of ironic that he's seen as this inaccessible literary giant when pretty much the hallmark of his style is its accessibility.
