Gene Wolfe: The Knight-Wizard duology. Might be available as a compilation, or as separate books The Knight and The Wizard. I also mentioned this in the previous thread, but it's so great that it's scary. For one thing, it has monsters that are really scary, while still being almost familiar. Giants that are much worse than just big humans, but that still need to eat. The one thing you have to understand about it is that it's not written as a horror book, but as a more realistic take on what it would feel to be the hero, the guy who never lies and always does what is right. I almost had to put the book down because what was right at the time was very far from good.
I've been trying to find Wolfe's other books for a while. There's Books of the New Sun, at least, and probably more.
