CODE OF CONDUCT by KRISTINE SMITH
I was a lot confused reading this book. I had the short-story prequel and really liked it. This is 15-ish years later. I'm not exactly sure what/who the female protagonist is - ex-soldier, document reviewer, alien, cyborg. The main bad guy (there are many) for this story wasn't really a surprise. Even though I'm confused, I still enjoyed the book. So I'm reading the rest of the series.
