This was a whole book from Ash's point of view. Ash's point of view! List of lifelong dreams, you're now half as long. Julie Kagawa was going to to leave it as a trilogy, but her editor convinced her to write The Iron Knight. This person is nothing short of a genius as, I don't know if I mentioned it, but it's a whole fricking book fro Ash's point of view!!!! 
 Also, if you usually skip over the Q&As at the end of books, you might want to rethink that with this book, there are surprise guest appearances !
