I have gone back to my favorite free SF source, Free SF Online, to take in an award winner while waiting for a book from the library. The Way of Cross and Dragon is a Hugo winner from 1980 that was added to the site while I've been away reading the Song of Ice and Fire. It was interesting to read a story from Martin that references dragons, but has nothing at all to do with Westeros.
This is instead a story of alternative religions. An inquisitor is sent forth to deal with an apostate believer who has invented a history and sainthood for Judas Iscariot. Not the first attempt to revive Judas' reputation--certainly The Last Temptation of Christ tried. It's pretty predictable, the inquisitor himself has doubts, but in the end there is a nice twist. It is very representative of Martin's work, solid but not really adventurous. I liked it well enough, you will too. 3 stars.
