This is definitely an outlier in the series, and I am glad/I hope that certain elements in this book won't be repeated as the series moves forward for logistical plot reasons. 

I never got comfortable with Harlow and Rukh's coupling because Rukh's inexperience with language, societal norms, and physical intimacy made me always look at him as a child. Therefore, any explicit scenes between these two seemed super unbalanced and unhealthy as far as power dynamic and fully informed consent go. Least favorite in the series so far, and I have read through book 6 at the time of writing this review.
