io9 has a fine writeup on Samuel R. Delany’s About Writing, the title of which should be an indication of its subject.
Take the essay on plot, for example. Delany goes off on some tangents, and also seems to be discussing scene-setting instead of plotting. But it all comes together, when he explains that the key to a good plot is actually visualizing the events of the story as if they really happened. And if you’re forced — by a cranky critique group, or your own conscience — to change the story’s events around, then you must revisualize the story all over again.
Interest: definitely piqued.
