The Fellowship of the Talisman Author:Clifford D. Simak On a parallel Earth perpetually laid waste by the Harriers of the Horde, a young man must ferry what may be a true account of Jesus's teachings to distant London. He's helped by a lonely ghost, a goblin, a demon, and a warrior woman riding a griffin.
It's, you know, basic fantasy adventure, not too heavy on the portentousness. Setting old-world, dialogue vaguely American. I did buy this book for the story, but kept it for the beautiful cover painting by Michael Whelan.
