** spoiler alert ** 
 This book was good. Like, it was a keep-the-pages-flipping good. But still not omg-this-is-such-a-good-book-gotta-read-it-over-again good. Honestly, I thought Cassian and Cora were gonna end up to be a good couple, not Cora burning with fury and wanting to kill him at the end. So.. that's my opinion.
