Yeah, don't it suck. ;^) It's really dated now, but the absolute best book I've ever read on the subject is Isaac Asimov's "Extraterrestrial Civilizations". It runs exhaustively through the solar system, then the galaxy and the universe and, making conservative guesses and assumptions along the way, comes up with a figure of the number of civilizations in the universe. Of course it's really just an intellectual exercise with no real predictive value, but it's a really fascinating trip.
