In my novel, the United Worlds (or UW for short) has made resettling the human race its business and, with Earth being mostly uninhabitable, its business model looks pretty promising. But why look for a new planet? Why not just live in space? I mean, we’ve imagined some pretty cool spaceships: Serenity, the Millenium Falcon, the USS Enterprise, and the Axiom. But even the people cruising around in their hover chairs slurping down cupcakes in a cup eventually wanted someplace to land.
