This is a great story about a young woman in a foreign country trying to make a living as a worker in a business that sells plasm, the life-blood of the Earth, to mages who use it for their own purposes. She becomes entangled with a revolutionary who is seeking to make a Utopian society and who needs a cache of plasm she has discovered to further his dreams. A quick explanation can't define this book. It introduces you to the heroine and the wonderfully realized sci-fi world she lives in and then lets the story unfold on it's own. Nothing seems destined to happend, forced, or cliche. The story just gets to the end on it's own. A wonderful book and an enjoyable read.
