The castle of the otter

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.
