I feel a little weird about rating this book 1 star. At a glance, it's not a 1 star book. The world is built competently and the premise is brilliant, and I know well enough that Jay Kristoff can dance his way through a story (he is, after all, half of the creative genius that created Illuminae.) 
 But jaysus, guys, this book was boring. I mean, it was boring as fuck. And I know that you're not "supposed" to rate or shelve DNFs, but I'll do what I want, since I spent 4 days trying to get through this and couldn't. I'm shelving this to reward myself for tireless efforts that yielded no payoff. 
 Full review to come, but I'm seriously disappointed in this one. I was really, really looking forward to it, and it totally let me down.
