This is a great book—comprised mostly of essays written about halfway through the publishing schedule of the four New Sun books—about Gene Wolfe's experiences and impetus and all kinds of other stuff about why and how he wrote such a masterpiece. It includes Urth humor and a lexicon of the words he used (every one of which is/was an actual word used at one time—a well known trait of Gene.) A must have, though a hard find, for any Gene Wolfe fan. And if you're not a fan, go be one, okay? It's way worth it.
