I just want to start out by saying man, that cover. So beautiful. 
 Now onto the review. 
 There was a lot to like here, but for me, it just wasn't enough. 
 The plot itself was great. Thea Robinson is the independent, feisty heroine that has the ability to manipulate people's emotions. She suddenly starts seeing things, nasty creatures that turn out to be a variety of demons. She finds out that she is Nephilim, a half human, half angel. Cam is a Power angel, a high ranking angel that fights demons. Cam's commander assigns him to properly train Thea so that she can begin fighting demons, as that is the job of the Nephilim. They don't get along at first, of course, and Cam finds himself attracted to her and loves that Thea has no problem with putting him in his place. It's a pretty standard PNR plot, but I really enjoyed the world building. Mostly. 
 I say mostly because there were there some problems. Why does someone with a paranormal gift find it so difficult to believe that there are angels? She's already seeing demons. There were inconsistencies that were so confusing. For example, in chapter eight, Cam tells Thea that his job is to help her learn to kill demons, because that is what Nephilim do. In the next chapter, Thea asks what would happen if she kills a demon, he tells her that Nephilim don't usually have the power to kill demons. 
 Cam, impressed with Thea's bravery and talent for fighting, thinks to himself that he had heard from other angels that Nephilim were know to be reluctant to fight at first, afraid of pain and death. That made me wonder why exactly it was their job to hunt demons. Especially considering other angels (such as Cam himself) kill demons as well. They seem more suited to the job. After training Thea for months, when she and Cam are finally fighting an actual demon, he has to tell her in the middle of it to avoid the demon's blood. Why didn't she know this? With a world as unique as this, a lot of explanation is needed. Perhaps it would have worked better as a full length novel. I wanted to know more. I thought this book did a wonderful job of putting a really original spin on an increasingly common sub-genre of PNR. What was there was interesting and exciting. It just wasn't enough. 
 I enjoyed the romance, but once again, I think it could have benefited from just more. The best part about "mate" romances is that it really gives permission for instalove. There is a legitimate reason for that all-powerful passionate attraction felt between two seemingly mismatched people. But there needs to be more. There needs to be the after, when they both realize that there is more to it than "because destiny". I don't think the book really went into that enough. What reasons were given didn't feel like enough to justify the relationship, at least to me. 
 This book had a lot going for it, but in my opinion, it never really reached its full potential.

 Just a side note here, but doesn't amazon own goodreads? Could they not synchronize their rating system a bit better? It feels weird to leave two different star ratings for the same book. SO CONFUSING. Okay, now I'm done.
