ok here's the quick and dirty of it... 
 After 5 books I'm SICK of hearing the following 
 "I need it yesterday" 
 "What the FUCK" 
 "She's fierce" (nope no drag queens in these books) 
 "She's fragile" 
 "Bug out" 
 And I'm sure there are more that my tired brain just can't regurgitate right now. 
 Grace was weak and on the edge most of the book, the poor thing. I felt that her romance with Rio went from zero to screw my brains out in less than 60 seconds. Not totally believable, but then again the whole paranormal twist the last two books had were a bit out there. I wouldn't mind if there was a paranormal element in the other books but nope, this came out of the blue and just felt forced and weird, at least for these books and these characters. 
 Story - 2.5 (it was ok, but probably not a relisten) 
 Narrator - 3 (enjoyable performance.
