OK, This is definitely my fav in the PsyCop series. The mystery and the romance are better. Also, I've noticed a slight change in the writing style. Am I the only one? It is more beautiful. Not beautiful "technically right", but beautiful "poetically". 
 And once again, like in Book 5, I like the fact that there is more balance in the importance of the two heroes. Jacob is not merely there to get Vic laid. He is a major actor in the plot. 
 Really, the characters are more developed. And I liked that. A lot. Jacob is more interesting than before, and I can't wait to see him in PsyCop 7. Gorgeous mega-manly commanding Jacob with new superpowers working for the superpower king? We can see the beginning of a good friendship between Jacob and Constantine. 
 Now, one thing bothered me: Why isn't anybody lusting after Jacob? Sure all the PsyCop books tell us that Jacob is very gorgeous and sexy, but it seems like Vic is the only one to see that... Seriously, I can't remember one person in the whole series, apart from Vic, who seriously lusts after Jacob. And Vic is supposed to be average (or am I wrong there) and everybody wants to jump him. I understand there is a kink element but even so... 
 And maybe that is the little unease I have with all this series. Until book 5, I did not even understand why Vic and Jacob were together if not for the sex. Not only did I not believe in their relationship, I did not believe Jacob was as amazing as the books said. I like The series because it is original, the universe the author created is captivating and the writing is good. But sometimes, I am frustrated. Still, I'll keep on reading it, because diving into this world it is like my own little astral experience.
