Science fiction is usually fun reading. After all, almost anything can happen since one man's magic is another man's science. There are limitations if the fiction is set on earth with regular earthlings - no werewolves, vampires, witches, or magic out of thin air. Yet even those might be found in a science story with the proper backstory. Some say time travel is one of these fantasy things, though for me, the jury is still out. Today's selection by Cotton E. Davis hinges on time travel and if you liked Connie Willis' "The Doomsday Book" rules for time travel, I believe you will like Cotton's set up as well.
