It hurts for me to give it a 4 star but I had to. 
 I love Julie Kagawa and the Iron fey series, but this book was just not a 5 star for me. 
 I guess my main disappointment came mostly from the characters. The main reason I loved the Iron Fey series so much is because of the chemistry between the characters. Their interactions and how they just fitted each other like a glove. It just helped made the whole story worked. The characters themselves were strong and distinct and it's hard not to fall with each one of them. On this book, however, the chemistry for me was not there and the characters took some time to like, let alone love. 
 Ethan, as much as I loved him to bits in the Iron Fey as a toddler, apparently he grew up and became a sour and cranky teenage boy. I understand why he became that way, the story's explanation made sense, but it made it difficult to like him reading him scowl all the time, about how much he hated how his life had become and how he hated the fearies. However, I began to like him as the story goes on, but still not as much as how I loved Meghan and how I rooted for her through her story. 
 The love interest, Kenzie, in the beginning, was just painfully annoying. I wanted to smack her every time she opened up her mouth. If Ms. Kagawa meant her to be that way, well she definitely succeeded in making me hate her. But, like Ethan, I grew to like her as well, although not so much. I know she's describes as dark haired, but I keep on imagining her as blond. Don't know why...huh. 
 The third main character is Keirran. I don't want to give too much about him, but if you've read the Iron King you'll know who he is. He was my greatest disappointment. I pictured him as a more a stronger character and more dominating I guess. He was sorta in the background. His interaction with Ethan was not as much as I hoped. I guess I kinda hoped for an Ash-Puck sort of interaction. Interesting, conflicted in a way and somehow full of emotions, whether like or hate. But their relationship lack all these things. Maybe it was too early to tell, I mean this is the first book of Ethan's series after all. I do hope their relationship will grow somewhat stronger, love or hate. Puck said that they reminded him of a certain pair in the past, which I assumed he meant him and Ash, but it was hard for me to agree with him on that. 
 Ethan and Kenzie's relationship was just okay. You rooted for them and I just wanted to smack Ethan for waiting to kiss her for so long. But it didn't give the tingling feeling that I felt reading Meghan and Ash or Meghan and Puck's romantic scenes. 
 Anywhoooooo.... despite all that. i still love the book. It is Julie Kagawa and the Iron Fey after all. I looooove that Ash, Meghan, Puck is in the book and that Grim had a big part in the book. It just made me missed them so much. The story was great and as always the storytelling was flawless. Definitely waiting for the next book.
