Really all I could think of while reading this book was a quote from one of Schwab's other books, and my personal favorite, Vicious. Plenty of humans were monstrous, and plenty of monsters knew how to play at being human. I really loved how this book dealt with the distinction between the monsters and the humans and blurring the lines between the two, especially how the 'good guys' were so set on being completely black and white in their definitions of good people and sinners that they ended up doing some things that I personally would call pretty monstrous I mean, how fair is it to send your soldiers out to fight and then sentence them to death if they have to actually kill someone in self defense? 
 The main reason I gave this 4 stars instead of 5 is because the entire time I was just thinking that it kind of suffered from what I call 'middle book syndrome', meaning that it doesn't really feel like a complete story in itself and more a way to get from point A to point B. But then it turns out it's actually supposed to be the end to the series and I'm not entirely sure how I feel about that. Also - SPOILER ALERT - I'm not sure how I feel about Schwab killing off all three of her main female characters in the last couple chapters either. Yikes. Although I do really appreciate the inclusion of a nonbinary character so good job on that.
