Holy shit, what's not to like about this book? You want a magic system based on consuming and burning metals? It's in here. You want an immortal God-King who rules with an iron fist? It's in here. You want chicks shooting people full of lead or copper, even? It's in here too!
I know what you're thinking. "Well, if all that's in there, I might as well give up hoping for killers with railroad spikes where their eyes should be. No book is that awesome."
But that's where you're wrong! This book IS that awesome. So read it.
