Dar is a good strong character who does make mistakes. She goes against all the rules to shun being a man's mistress to befriending an Orc. The women call her an Orc whore, thinking there is a sexual relationship with Kovok-mah, the shunned man is determined to get Dar at all costs and the Orc clan also disapprove of this new friendship. As the fighting grows more intense Dar has to keep her wits about her to stay alive.
This is certainly dark fantasy, and a very grim world for the female slaves. There are the women who betray their kind to tell tales to their soldier lovers, the soldiers who are evil rapists and the brutal fighting Orcs with their own rules that are greatly feared. But the author paints the picture of the Orcs as a race who are unaware that their strength is being used to save soldiers risking their own lives, and we start to see the different personalities of the Orcs coming through in their interactions with Dar. The monsters have feelings and the true monsters are the soldiers themselves.
This was different from anything I had read before and it doesn't go too heavily into the fantasy side. It is more character based than that which is why I liked it.
