Guild Hunter Elena Deveraux is a vampire assassin. When vampires go rogue and stop following the orders of their Angel masters, Elena is called in to clean up the mess - whether it be as a glorified vampire bounty hunter or slayer - she's there with her trusty knives and other Guild sanctioned weapons. 
 When bodies start piling up in the city of New York, Elena is called in to track the monster responsible... but things aren't as they seem. The murderer is an Archangel turned bad and her new boss is none other than Raphael, a dangerous angel who gorgeous but deadly. 
 I loved the world created for this book. Angels are the ones who turn humans into vampires? It was something I've not come across before and I liked how the human, vampire and angel worlds all interacted within the one society. There were other little things that I liked because they added to the differences between the real world and that of the Guild Hunters - like the earrings signifying marital status. 
 I was slightly disappointed with the romance. I couldn't understand why Raphael and Elena would want the other - Raphael is an immortal who has been alive for thousands of years and yet for some reason he unexplainably wants Elena who he constantly refers to as his toy. I never really felt like he wanted her as anything more than a plaything. And Elena is drawn to Raphael but she puts that down to his incredible lethal beauty and angelic powers. She even goes as far as to suggest that he enjoys rape after they share a brutal kiss... and then makes out with him a few days after that. I couldn't believe that Elena, the woman who claims that she would put her life on the line for her sister-in-all-but-blood, Guild Director Sara, would engage in a sexual relationship with the man who was threatening Sara's daughter's life every couple of chapters. It just did not compute for me. 
 By the time end of the novel came around I was hoping that I could believe in the two of them as a couple but I didn't feel like any of their previous issues was resolved. They weren't a romantic couple in my eyes and I wouldn't put it past either one to stab the other one in the back when they weren't looking. 
 In terms of drama and action - there's a lot going on. There were a lot of characters introduced and a lot of mystery still involved regarding them. With respect to the minor characters, I would consider reading the next book in the series.
