This series has been one of my favourites this year, Charlie is a character that I deeply enjoy and Reyes (though he had his ups and downs with me in the last book) was finally free and I was looking forward to reading about what he plans on doing in this book after being on the run for 3 books 
 I was a little disappointed with this book 
 There was something missing about it, the spark that the other books always had. This seems a rushed to me 
 The author has a talent for creating interesting characters and she introduced one new character named Hedeshi who I found really intriguing,(view spoiler)[ he was dark, full of mystery and charm and readers could tell he was no ordinary demon, you feel he's more high up in the ranks than an average demon but the thing is, we never knew what he was, a general, captain and at one point I thought that he might be Reyes' brother if he hadn't referred to Reyes as "My Lord" 
 He dies before we get a chance to explore him more, which really disappointed me 
 (hide spoiler)] 
 Charlie's character bordered on being Mary-sue in this book due to the fact that she was the "one" with all the power yet didn't know how to use it and therefore was useless, (view spoiler)[until towards the end where she indeed did use a power. (hide spoiler)] If it wasn't for her flaws I could have called her a Mary-sue 
 The emotions that were in the last book which had my eyes' watering when her relationship with her father got damaged was also absent, it wasn't as convincing as the last book. I will admit, Charlie was a bit TOO harsh on her father during the confrontation but perhaps that is how she is made. 
 Regardless of how this book wasn't as good as the last ones, I am still looking forward to seeing where the author will take this book, I really thought that this was the last book but I see that there are two more to go. I think what I'm looking forward to the most is when Charlie and Reyes come face to face with his father.. His real father! 
 P.S oh and that reveal at the end showing who moved in the apartment was so obvious!
