Carrera's private war against terrorists has long since become an exercise in nation building and a war against those whose presence and aims made the terrorists possible to begin with. As such Carrera tied membership in the legion with the governing of Balboa. But Balboa is a small nation under occupation by a peacekeeping force that force represents powers whose way of life is anathema to all the things Carrera believes in. Indeed the Transunion is not just the direct enemy but pretty far down the road of being the hereditary classed society of the privileged few ruling the masses that is now Earth. So Carrera needs bodies as Transunion is many time more populous than Balboa. To get those bodies Carrera needs women. But past attempts to use women as combat troops has not been overly successful. The question is how to do it right. This is that story centered partly on one such solder. - I did not like this book as much as the preceding ones but I liked it. I would probably have like it more if there were fewer intermission chapters that filled in on what was going on in the big picture, but then again the big picture is necessary for context. I just found the personal struggles, fears, doubts, and ambitions of Maria as she joined up, went through training, and faced combat under difficult and morally trying circumstances compelling. If you like the series you should like this book. If you have never read any of the series you could read this one as an introduction then go back and read the previous stories.
