This is the tale of Joe Fernwright, a professional ceramic repair guy from a future Cleveland who is recruited by the alien Glimmung to travel to Sirius Five to help him raise a cathedral from an underwater ocean. I really enjoyed this one. The novel is short, only 144 pages, so the secondary characters aren't thoroughly fleshed out and the plot isn't complex, but there is so much humor! I laughed more during this book than any other PKD novel.
