In this book, Moon creates another strong female lead with a military background.  However, she takes her someplace a little different than Harris and Esmay.  Having read all of her previous books, I was pleasantly surprised that the usual plot twists had unusual resolutions.  The characterization is good, but the plot moves a little slowly for my taste.  All in all, the high quality entertainment that I expect when I pick up a Moon book, but not such a spectacular story as to merit five stars.
