I'm looking for some good science fiction books. Preferably some in the cyberpunk genre. Books that deal with small people going against huge corporations or just something bigger than themselves.

I don't mind politics in my books, though I don't want them to get out weighed by them. I'd prefer for the book to focus on a character or a small group of characters in this world.

I'd heard some good things about the Takeshi Kovacs series and the William Gibson trilogy that starts with Neuromancer. Are there any other good ones out there?
