I'd like to rate this book higher than I have, because I'm pretty sure I should have enjoyed it more than I did. 
The premise is such an interesting idea (though I didn't realise the title wasn't a metaphor for a little while. That's on me) and the way it was written was snappy, packed full of adventure and tense scenes and all very myterious and exciting. All the characters were very unique and the author did a brilliant job of establishing their personalities really quickly. But I just had absolutely NO motivation to keep going. It wasn't even slow paced! I don't know why, but it never clicked with me at all, and I found it such a drag to get through. When I was reading it I was enjoying it and found it interesting, but then I'd put it down again and just not really care to keep going. 
I'd definitely recommend it if you enjoy modern takes on fantasy! A really interesting idea that I wish grabbed me more.
