3.5 stars. This is a really fun read. It is definitely on the light and fluffy side so if you're expecting serious, heavy historical fiction you'll be disappointed but if you want to enjoy some Napoleonic France era spy hijinks, witty writing, vivid and spirited characters, and romance this book will hit the spot. This book is really quite silly at points but it has a lot of charm. It is like a big dumb puppy in book form. 
 The chapters set in the present day are totally lame and unnecessary but they aren't a huge part of the story so they don't detract too much from the overall reading experience.
