Full review here. 
 This book is exhausting in the way that all Julie Kagawa books are exhausting. When I finish one of Julie's books, I just want to take a nap. Sure, that may be because I finished this book at midnight, but I think it's much more likely that it's because reading one is so incredibly emotionally draining. Not to mention the descriptions of the action sequences make me feel like I'm there. 
 One of the best parts of this series by far is Kenzie and Ethan's relationship. I loved Meghan and Ash together, but their relationship was so turbulent. I'm not saying that Ethan and Kenzie don't have rocky moments, but there is a calmness, a peace when they are together. They're such a good fit. At the risk of being completely cliche, they're adjoining puzzle pieces. Kenzie softens Ethan, despite the fact that she's totally a firecracker herself, and Ethan strengthens Kenzie. His brand of protectiveness of her is very refreshing. When Ethan pushes Kenzie away for her own good, it's not him being misogynistic; it's because he really is concerned A. that she, a total newb to the world of the fey, will get sucked into some messy fairy deal; and B. the potential disastrous consequences any of their adventures could have on her health. But the awesome thing is that Kenzie allows it to a point, then she puts her foot down. There's a moment in Iron Traitor where, for Kenzie's protection, Ethan blatantly insults her right in front of her. Kenzie gets that it probably saved her life, but she, like any normal girl whose boyfriend just called her names, is upset by it. Ethan swallows his pride and apologizes, and their exchange is one of the sweetest things I've read all year....
