People make a big fuss about Book of the New Sun, but the narrator being reliable or not barely changes anything. It's overrated, and often questionable. It's the same thing as many characters in the book being named after saints. So what ? "Umm... Errr.... Nothing I guess. It just makes me feel better, a part of an erudite circle. I praise the book because it makes me feel superior to others."

A much better example is Flowers For Algernon by Keyes. In the book, you can clearly see the narrator interpreting the same events differently as his understanding changes.

Another example is Canticle for Leibowitz by Miller. It's a book about people trying to recover from a nuclear holocaust. A war that destroyed nearly all traces of civilization, reducing humanity to illiteracy, swords and bows. A monastery is scrambling to find and preserve any bits of knowledge. Their understanding of the past is very limited, and they often interpret remains incorrectly.
