This book has all the problems you typically see in a 1st book of a new series. I like to call this "1st book syndrome" meaning that more often than not you will find a 1st book not to your liking.
Considering what this book is based on though (fallen angels), I was hoping to find that the plot, premise & characters would not be so simple. That the emotions, the issues and most of all the characters would be conflicted and in a convincing manner. You would think that what these creatures/people are dealing with and facing, what they have faced would not cause things to come about or be resolved in such a, for lack of a better word.. "Simple" easy manner.
I did not care at all for the lead female. she was said to be someone who is most likely in her late 20's maybe thirty, but her reasoning on all fronts would be that of a teenager. I did not like this at all. Raziel of course was hot as he was suppose to be but seriously lacked that thing that is signature of an Alpha male.. He came off just as whiny as Allie in alot of ways.. Given that, some of the action is what led me to keep reading, and I was a little intrigued by Azazel.. But I've always been intrigued by the fallen Azazel..
There really was not much world building in this book, and usually that is what you would find wrong with a 1st book, just trying to get a feel and understanding for the world these characters reside in. But no, that was not a problem with this one. The problem was everything else.. I am not sure if I will continue this series or not.. But I am guessing you really would not have to read this particular book in order to read the 2nd and 3rd. Unless you just want to know everything that has happened before starting the 2nd and 3rd book.. Other than that I would not recommend this read.
