Ever have a book that you simultaneously adore and are disappointed by? That's kinda my experience with Glamour in Glass. 
 On the one hand, Glamour in Glass takes the main conceits posited in Shades of Milk and Honey and expands on them wonderfully. I adore being in this world of Regency England where we can do magic and I adore Jane, especially her interactions with her family and newly wed husband, Vincent. I love watching Jane navigate society's expectations along with the expectations of her family and herself for how a woman should act and what her priorities should be. I love the sense of intrigue the book brought what with the new plot of Napoleon threatening war. 
 On the other hand, for a book set in Regency England, we AREN'T IN Regency England. That majority of the book takes place in Brussels or France and although I did enjoy the contrast socially between women's place in England and women's place in France/Belgium, I quickly longed to return to England because the setting felt so different. The well known setting of Shades of Milk and Honey was part of the reason I loved the book so much. We took a place that culturally we are very familiar with if you seen but one Jane Austen adaptation and mixed in magic. We definitely still get some of that in Glamour in Glass due to Jane's sensibilities, but it strayed too far from that setting for my liking which came at a great disappointment to me. There also wasn't much romance to it. I know, I know, Jane has been married, what use is there to courting? By romance I don't necessarily mean courting. Due to plot events, a great part of the book is spent with Jane and Vincent being awkwardly stiff with each other. My stance when it comes to romance has normally been "stop with all this love crap, there's a war going on!" but in this book I found myself saying "Napoleon, stop with this war thing, I just want to see the two of them be in love and deal with their relationship!" 
 Some of the problems I had in the first book remain firmly in place. The ending feels rushed to me and in intense action scenes, I often got lost. I am thinking the latter point is due to the author's use of pronouns. Upon my 3rd reread of a certain scene I noticed that instead of proper nouns, there were a lot of "he did this" "she reacted thusly" (obviously worded much better than that). Maybe the lack of distinct pronouns confused me. It is but a theory. 
 Please do not take my criticism as a sign that I disliked this book. I loved this book. I love this world. I happily will keep reading this series for as long as the author writes them. But these were points that left me disappointed because it could have been PERFECT. Well, not perfect. No book is perfect. But better than it is, which is still pretty great.
