In honor of World UFO Day we are reprinting a Table of Contents featuring a series of alternate endings submitted by fans to complete Roger’s unfinished sci-fi tale, “The Thinking Molecules of Titan.” Click on each author’s name to be directed to the full article. All illustrations are by Krishna Bala Shenoi. As I sat and re-read each submission, I was again impressed by the work they put into writing the endings, and I hope that somehow, somewhere, Roger, in his vast infinity of bliss, will connect with them as well.
