Publisher's Summary

On planets, they say, water always runs downhill…Serena had no way of knowing if it was true. She had never been on a planet. Not in the brief million or so years she had been aware. Neither had any of her acquaintances. The very idea was ridiculous. Very few Grand Voyageurs ever got a chance to see a planet. And yet, even among them, the ancient truisms were still told. That which goes up must fall, and will…She had been willing to take their word for it. The clichés came out of a foggy past. Why should she question them? Why should she care?
