The Iron Warrior by Julie Kagawa

— feeling amazing
The Iron Warrior (The Iron Fey) - Julie Kagawa

Epic!
Though about halfway through, for just a fraction of time, what I was reading was absurd.
I'm so glad that feeling was short-lived because most of this book I had trouble putting down. 
I was in the Ash fan club, all this time, but now that Ethan is 18 and kicking ass, I may be in that club too! 
You know those reads that you don't want to end? This is definitely among that list. I think this is supposed to be the last in the series, but the end was left wide open for more. I don't know why the author wouldn't continue with Keirran now. He still has so much left to tell us fans. Well, if it does get written, I'll be sure to be grabbing a copy.
If you haven't read this series, there's something wrong with you. Okay, maybe nothing is wrong with you but you need to get with the program and read it. Seriously.
