"Roberts gives us many sharp insights into religion, history, philosophy, and popular culture - in particular, of course, our own patch of popular culture: science fiction. . . . These are large topics for a book of 193 pages, plus index. Within its confines Roberts has done far more than take the four horsemen out for a canter: he spurs them to a gallop and makes them break sweat. The show is well worth the price of admission, and sends us away deep in thought." --Shoreline of Infinity
