The good:

- I love the idea of a duke getting mistaken as a footman and falling in love with the heroine that way. It was handled decently enough.

The not-so-good:

- This very much feels like the third book in a series and doesn't read very well out of order. A ton of previous characters were mentioned and how they met this person or shot at that person. It was a lot to keep track of and weighed the main narrative down.
- The letters play a more minor role in the story than I was hoping.
- I'm not a stickler history-wise, but some parts seemed unrealistic to me.

So... enh. I'm not going to swear off Boyle but I doubt I'll be revisiting this series.
