The Starmen of Llyrdis

I'm an interstellar trading lord, how about you? An earth man finds out that we aren't alone, and he is one of the few that has the genetics for space travel. Therein lies the conflict, this genetic issue. Those that have it, and the conservative faction would rather like to keep their moneymaking and power monopoly thanks very much, while a rebel group would like for everyone to eventually be able to do space in a big way. The previous leader of which has disappeared into the depths of space. Still, pretty reasonably handled by Brackett, and worth a look. 3.5 out of 5
