Three Novels
An excellent collection of SFWA Grandmaster Damon Knight's always-excellent stories-three short novels in this case: Rule Golden-what if the Golden Rule were enforced in reverse by some force-the bad things you do to others are done to you? Natural State-are cities doomed by genetic engineering? The Dying Man-what would it be like to be immortal... then suddenly find out you'd become mortal? (Note that Rule Golden and Other Stories includes these same three, plus two more.)
