Another Hugo suggestion: The Gospel According to Science Fiction

The nonfiction book The Gospel According to Science Fiction by Gabriel McKee is a very worthy candidate, in my humble opinion, for the 2008 Hugo Award for for Best Related Book. Check out what I had to say when I first read the book last year.

(The 2008 "Best Related Book" Hugo is to honor "a work whose subject is related to the field of science fiction, fantasy, or fandom, appearing for the first time in book form during 2007, and which is either non-fiction or, if fictional, is noteworthy primarily for aspects other than the fictional text.")
