The title and the cover intrigued me. I love a good spy novel but this is really a fun and frivolous thing. On the back it is compared to Jane Austen. To be honest, had a read that, I probably wouldn't have read this book. I loathe Austen - once you've read one, you've read them all.
Happily I didn't find Juliana much like any of Ms. Austen's so -called heroines. She is bright, resourceful, inquisitive and not looking for a husband! Quite the contrary, she is going to London for the season in an attempt to find a publishing house to publish her scientific works. The fact that she meets a handsome spy along the way really doesn't play into her goals initially. Even when she does work out an arrangement with Mr. Northam, it is to help her friend with a beau not promote herself.
A light enjoyable read. If you enjoy romance and a Victorian setting, this may be worth checking out for you. I gave it three stars.
