This was the first story I read in this series about the future settlement of Mars. As an introduction to the other "alien" race inhabiting the solar system, it set the stage for some potentially intriguing story lines. Galatea's character was utterly alien, and yet understandable. There was an internal consistency to the ethical rules she and her kind followed, and by the end it's clear that like all of Stornoway's tales of Mars, there's a lot more that can be told in future episodes.
