 What sets this book apart from others in the Iron Fey series is that it is told from Ash's point of view, not Meghan's. I was a little wary at first. I like when Meghan tells the story. Over the course of three novels we've really seen her grow as a person and I was worried that the Iron Knight just wouldn't have the same feel without her. Well all my worrying was for nothing. Julie Kagawa does an amazing job of shifting the viewpoint. It doesn't feel forced, it feels natural, like Ash has been telling his story the whole time. 
 This story is incredibly well put together. Not only does it tie up all the lose ends of the previous books it also goes back and fills in some earlier details. In particular we get to find out more about Ariella, her relationship with Ash and their friendship with Puck. I don't know about the rest of you but I was always curious about Ariella and wondered if she was always going to be the elephant in the room, so to speak, for Ash and Meghan. All of those questions and more will be answered! 
 This is also an incredible book for character development. The first three books are all about Meghan (as they should be) but this one really focuses on Ash, and to a lesser extent Puck. We really get to know them and their history and you're really able to connect with them on a more personal level. Whether your Team Puck or Team Ash doesn't matter so much in this book. You'll be cheering them on and easily fall in love with both of these amazing boys. 
 Overall this is a beautifully written book and the perfect end to the series. As always Kagawa weaves together an incredible fantasy land, where magic and mystery exist side by side. The characters are lovable, creative and full of life. It's a bittersweet moment when a series you love comes to end so perfectly. You want it to keep going but you know it's right just the way it is.
