*** I received an ARC from Skyscape through NetGalley for an honest review. Expected publication date: 2/24/2015 *** 
 I was really looking forward to reading this because there are not many books out there where the gargoyles are the main focus, there are a handful, but they are far and few between. And being presented with the opportunity to read about a world where gargoyles were supposed to be protectors of humankind, but instead turned out to be predators of mortals and need a mortal to keep them in check was something I couldn't pass up. But while it started out promising, it soon turned flat for me. I was looking forward to a story filled with the history of the gargoyles and why it is a mortal who is the only one who is able to control them, but didn't get that. There was more about Kate's ex and stalker than true background on the gargoyles, sentinel and the supernatural world the story was set in. 
 The history of the gargoyles wasn't anything spectacular, they were to protect humankind but something went wrong. That's really it. Nothing more. The way a sentinel is chosen is a simple one, but it was never truly developed to explain why they were connected to the gargoyles. There was no background as to how it started and Kate, or Ian just accepted it and never tried to dig deeper into it. And the reason for a sentinel? Yes they control the gargoyles, but what they actually do in order for it to happen was just a let down. 
 The characters all had the potential to be interesting but I just could connect to any of them. Declan is the puppet master of it all and while for the most part is straightforward, he doesn't give you all the information needed. Von Hiller is Declan's second and flip flopped between being mysterious and being the one to be Declan's mouthpiece when needed. Kate, who should have been the most interesting of all since she is the chosen one, just didn't do it for me. Her hesitation over taking the position of sentinel I understood but how she dealt with her ex-boyfriend and her stalked just had me shaking my head. Ian, was probably the most likeable of the characters, but he was just too accepting of it all and using his occupation as a reason for it wasn't satisfying. Then there was the addition of the supernatural elements. I understand that they were there to lend to the supernatural feel of the story, but their link to the gargoyles was negligible. They knew of them, but we never know just how they truly feel about them. 
 This story had the potential to be a great one, but there were too many elements involved that didn't serve to strengthen the main plot of the story for me.
