Roger Williams has published a novel (novella?) on line. You can read it for free in several formats (html, pdf, etc), but he's also got a tip-jar.
For some reason, the title of his novel, "The Metamorphosis of Prime Intellect", struck me as a bit cheesy. But there's nothing cheesy about the story itself. In fact, it's one of the better science fiction stories I've read. Definitely better than a lot of crap I've paid good money for.
Anyway, I recommend it: Support the independent underdog!
