Ep 008 - Dune, by Frank Herbert
Good science fiction uses fantastical characters, locations, and technology to comment intelligently on problems that we face in the real world, but the best science fiction can also do this in a suspenseful, entertaining, adventuresome way. Frank Herbert's Dune gets most of the way there, but Andrew can't help but wish he had read it for the first time as a teenager instead of an adult.
