This list is not at all comprehensive. These are only novels or short stories that I have read. If anyone thinks a book or short story should be added to the list, email me, and I'll look into it and most likely read it!
-Perelandra, by C.S. Lewis
-Out of the Silent Planet, by C.S. Lewis
-A Canticle for Leibowitz, by Walter M. Miller
-"Scanners Live in Vain," by Cordwainer Smith
