Enjoyable futuristic tale about an exoplanet composed mostly of water and populated by human-like beings. A spaceship lands, looking for candidate planets to colonise, since Earth has become irrevocably polluted. A grim warning of what could happen in reality. I liked the description of the planetary beings' rather solitary society and their approach to decision-making and democracy. The ending was perhaps a little rushed for my taste, but overall this was an entertaining read.
