2.5 stars. 
 All right, I'm not getting anything else done, and a nap seems to be eluding me, so here goes. 
 I had a devilish hard time reading this book. I just couldn't connect with the writing at all. I found it extremely dry and explain-y, and my mind would wander any time there wasn't dialogue. Which was, ah, most of the time. 
 Now I have to say: I think this is my fault too, and not just the book's. Sometimes a writing style just doesn't connect with my thinking style, and that isn't anybody's fault. I really need characters to connect to, and 3rd person omniscient keeps you at arm's length. That said, it's good for much of what she was trying to do, which is action. 
 I am probably in a minority here, but I tend to skim action. I find it blindingly tedious. Especially when it isn't even human action but somebody piloting a shuttlecraft into the airlock, or bullets whizzing around. *snore* 
 Much of this book just wasn't my thing. The parts that MIGHT have been my thing kept feeling muted and truncated. For example: (view spoiler)[Waverly having invasive, non-consensual, egg-stealing surgery. Her reaction to that was so... nothing? Or maybe it was all done in explain-y writing and I zoned out. I dunno. Same with Kieran being starved. I felt like the author had done a LOT of research on what happens to your body when you're starved, but somehow the effect felt really clinical to me, and not so horrifying. (hide spoiler)]. I came very close to putting this down for good many times because I just wasn't feeling it. 
 Absurdly, everything that came in the book's "Epilogue", I found much more interesting and compelling than what had gone before. Trauma changing people? PTSD reaction to religion? Philosophical implications of what Kieran has been up to? Sign me up! 
 And then, of course, the book was done. Huh. Will I read the next one? Dunno. Maybe, if I read some reviews that convince me we're getting inside the characters a bit more, and not just scraping our shuttlecrafts across the hard metallic surface of the world. 
 (O hai, cold meds! You make such good metaphors!)
