It took time to get into the crowded confusing world of the overpopulated space station, but once it got going, the story was a lot of fun. Earth's terraforming projects have gone disastrously awry and too many people have been waiting on space stations - no safe planets to emigrate to and Earth won't take them back. 20 odd years later, an ambitious scientist shows up, ready to save humanity, but she must first deal with station culture and politics. The romance does get a bit goofy by the end, but I enjoyed it thoroughly.
