Some reviews said that this book could have been better. Hmmm, probably. But the thing is I do not think it was meant to be an epic tale like the previous Iron Fey books. I think this book was intended as a candy for Team Ash. In this view, this book really went for the home run. 
 The previous volumes of the series reminded me of Lord of the Rings and Midsummer Night dream. (Maybe a bit of Alice in Wonderland as well). The Iron Knight reminded me of a movie instead: What dream may come. You know the one with Robin Williams going to find his wife in Hell? Yep. Ash battles all sorts of creatures and while some author parade creatures like a dictionary (or a D&D book), Julie Kagawa only showed us her wild imagination. :) 
 Ash's love and devotion is something to witness. A true knight that is. Sigh. 
 I liked how we saw the world through Ash's eyes. In battle, he would analyse everything like a warrior. It's very different from Meg's point of view. 
 Like I did before, here are questions to the universe: 
 1- Every time Ash was questioning his promise to Meghan to find a solution for their being together, his essence began unravelling. How is it then that his vow to kill Puck didn't do the same? Yes I suppose Ariella was still alive. But he did not know that. And I suppose he was trying to kill him. But only trying. Puck said it himself that he was only toying with him. So yeah, maybe I am a bit paranoid I guess. 
 2- There is one other thing: I always thought that without a soul one couldn't fall in love. But I guess it works here... 
 Oh gosh I kinda wonders what will happen to Puck now. No chance that we'll know more? *puppy eyes* 
 Well this would make my 2012 summer vacation quite enjoyable. We didn't have much money to travel this year, so thank you Julie Kagawa for making my imagination travel to the end of the World.
