QUOTE : THE ART OF fiction is a wide-open sea of possibilities, in which the author is a wave-tossed ship along for the ride. And what a glorious ride it is! On the other hand, the craft of fiction puts that same ship under the expert guidance of a captain who knows how to decipher his chart of those seas and then furl, trim, and jib his sails so his ship will carry him through the story on precisely the right course.
