Query: An interesting alternate history story.

It is not without its flaws (I agree with an earlier review in that the modern characters could have used some more personality flaws), but ultimately, I found it an interesting exploration of an intriguing idea, and am looking forward to reading its sequel. However, I would like to address both HaloJonesFan and J. Reed: lighten up! HaloJonesFan- This is not some parody of conservative fears about gender roles being upended, but a simple military thriller set in a very unique setting (I also disagree with your assessment of it as full of mindless carnage). J. Reed: calling HaloJonesFan a "lefty loon" and assuming that he is a "lefty-elitist" who feels that anyone who likes this is stupid is simply insulting and simpleminded, and calling him that will do nothing to improve his opinion of your worldview.
