Hugh Cook offers a lot of his own sci-fi novels for free. Here's the link:
http://zenvirus.com/alphadiabolical.html
Unfortunately, the site suffers from an overly complicated design, as if assembled by a monkey on steroids, and looking much like one or two other sites already discussed in this thread.
You need permission to download these Sci-Fi novels, but they're freely available for online reading.
I'm not familiar with his writing, but it's free online reading!
