This turned into a very engrossing story, with many philosophical questions being raised about what constitues "human", issues of ethics and independence regarding AI's, and the struggle between acting on duty versus acting on one's conscience. And there's a very bizarre love story, too.
I have to admit that much of the science/physics was over my head, but I appreciated the gist of it, nonetheless. Reminded me of a hard-boiled, noir version of Tepper's After Long Silence, and also more generally of Altered Carbon by Richard K. Morgan.
Masterful world-building. Fully formed set and setting painted with a maximum economy of brush strokes, peopled with three dimensional characters, some of whom can scarcely be called human but for the heart at their cores. Todays far frontier of quantum physics is the infra-structural under pinnings of entire interstellar civilizations, civilizations fast approaching a collision at the crossroads of history. In the center of that crossroad, used and abused to the point that she can barely tell who she is stands a soldier..
Excellent. Moriarty does a wonderful job revealing both the story and the science in a way that keeps the reader interested while not overloading him or her with the fascinating science upon which the story is built.
