I feel like maybe I would have liked this book a lot more when I was younger. I loved the intro, but it seemed to feel a little more predictable and not as engaging after that. Many parts of the story felt very detached and I couldn't find hardly any character to actually "like" or even relate to very much. It felt a little like a book that didn't know where it belonged--it should have been erotica from some plot points, but always shied away from anything actually explicit or tantalizing. At the same time, it seemed to use sex torture as a shock value device, but only ever implied and never delved into anything, really.
Overall, it just felt mostly hollow. I'd still consider listening to the next book in the series, but I didn't jump at the chance and decided to listen to a non-fiction next.
