The blurb made it seem that she would spend a goodly chunk of the book getting herself back to the team or civilisation or whatever but actually it's only a few chapters in a story, though it is a pivotal point in the story for the heroines growth.
Levi Butcher leads a paramilitary unit of macho men and into this mix his boss puts a geek, and a female geek at that. She, Jina Modell, and the other geeks assigned to other teams, are unfit and would not be able to keep up with the team so they set about fixing that, trying to break her, but she refuses to break and becomes part of the team. After a few missions she ends up left behind and has to get to safety, ignoring pain and the fear of being trapped behind enemy lines.
It's interesting and the characters are well drawn, even if Levi Butcher comes across as being a bit of an ass sometimes while he tries to convince himself that the only feelings he has for Jina is that of a co-worker. I also had some issues with the resolution as it was a bit pat and easy. Still an interesting read with characters I was rooting for.
