The Empress of Mars: A Novella(2003)

David G. HartwellPatrick Nielsen Hayden

"There were three Empresses of Mars. The first one was a bar at the Settlement. The second was the lady who ran the bar; though her title was strictly informal, having been bestowed on her by the regular customers, and her domain extended no further than the pleasantly gloomy walls of the only place you could get beer on the Tharsis Bulge. The third one was the Queen of England."
