The Narcissus Plague, by Lisa Goldstein

The Narcissus Plague was nominated for a Nebula in 1995.  What I liked best about it was her reason for writing it--"I wrote 'The Narcissus Plague' after a week where everyone I met seemed to talk about nothing but themselves, and I began to wonder if there was some sort of plague going around."  Nice.  Give yourself a little treat.  3 stars
