Glamour in Glass by Mary Robinette Kowal

This is the book that follows Shades of Milk and Honey and continues the story of our Jane and her husband.
In this book they travel to France and get entangled with Napoleon's army.

This book was much more involved and exciting than the first book. The magic that Jane is mastering is much more useful in this story as well--in the first it was used only for entertaining.

I've enjoyed both books a lot.
