I'm not sure why this book received so much hype. The author is a skilled writer, but the book never realized its potential. It had an interesting premise, a variety of characters, a solid sense of place – but it just didn't go anywhere. In addition, there were some lengthy sections steeped in physics that seemed more like they were there to showcase how much the author had learned about the topic rather than serving the plot/point in any significant way. Or maybe it all just went over my head.
