I have to say this is the first one in this series, in a while, in which I was actually interested in all of the storylines. It was a little slow to start, and Tohr royally pissed me off numerous times with his stupidity and omg John Matthew and Xhex too, but I'm glad everything wasn't just happy happy hunky dory even with couples that you thought were set already. 
 SO much happens in this book. It's probably one of the more difficult main romantic pairings in the series since both sides have a LOT of insanely heavy baggage (similar to JM and Xhex in that respect). I would've liked to see No'One struggle with her past a bit more in the beginning of everything because I don't think it was quite as realistic as far as post-sexual assault victim ptsd, but it has been like a couple hundred years since it happened so I don't know how that would change things for a victim's mental state. (Plus the author had the same trouble with dealing with Xhex's situation in a realistic way previously so I guess this comes as no surprise.) 
 I think Tohr's journey was perhaps one of the more realistic feeling emotional journeys in the series for any character, which was really exciting to read. 
 I recommend this one if you liked Bella and Zsadist's story, and/or John Matthew and Xhex's, you'll like this one too. I would NOT recommend this if you've never read the previous books in the series as this book in particular begins in the middle of several storylines that have been talked about for the past 2 or 3 books.
