This was very interesting especially since it's an erotica/sci-fi/dystopian book. I never really read a book like this so I really appreciated the world building but I would have liked just a little bit more.
There was a lot of SEX which didn't surprise me. The women are very free to choose what they sexually do and I'm all for ménage scenarios if executed nicely. But I do think that the sexual freedom was chosen a little too easily. It seemed like Noelle would just meet someone in Sector Four and then all of a sudden perform a sexual act to/with them a few minutes later. I would have a liked a little more build up in these types of scenes. However, this is a fantasy and erotica! So, I shouldn't harp on this too much.
Overall, this was a fun and interesting read and a good escape for readers in the mood for SMUT. I will read more of this series.
