Glamour in Glass follows the Vincents as, early in their relationship, they take a trip to the Continent to study and work glamour together with one of Vincent’s friends. This time, Kowal explores the way her magic system might affect pregnant women, while playing with the historical backdrop as well. The Vincents find themselves at risk from Napoleon’s followers, and their trip becomes less about the glamour and more about spying out what exactly might be happening — perhaps even betrayal from the people they call friends.
This was where the series took off for me, the first time I actually read this book, and while I’ve come to appreciate the first book, this is still where I would say the series really gets interesting. This is where Kowal starts to work out the implications of the magic and how it changes society, eclipsing the primarily romantic plot of the first book. I’d say the third book is even stronger in that sense, but this one is certainly nothing to sniff at, either. It’s all up from here, and this has really become a series I think about fondly.
