Three short novels by science fiction legends-Poul Anderson, Gordon R. Dickson, Robert Silverberg-all inspired by the same theme: What kind of world might exist where the basis of faith is replaced by certain knowledge? What if God proved He exists by stopping the Earth from spinning for 24 hours? Faith wasn't enough. Maybe it should have been, but it wasn't. And when science didn't find any reason to suppose the world was more than atoms and chance, humanity started slipping back into chaos. The world needed a sign-scientific proof, the only sign it could accept-that God lived. Then suddenly, as in biblical times, the sign was there: "...for a day and a night... the earth moved not around the Sun, neither did it rotate." What happened the day the sun stood still? Three outstanding science-fiction authors explore that theme, probing the reaction of modern man when confronted with a miracle, in three entirely different but equally absorbing stories, never before published: A Chapter of Revelation by Poul Anderson; Thomas the Proclaimer by Robert Silverberg; and Things Which Are Caesar's by Gordon R. Dickson. In doing so, they answer the question posed by science-fiction master Lester del Rey in his foreword: What kind of world might exist where the basis of faith is replaced by certain knowledge?
