There's a particular level of niche nerdiness for which these books scratch an itch. Yes, I WOULD like to think about the how the suspension of habeus corpus affected the average Londoner (and their love life?)
This series is interesting precisely for how careful it is not to play into the lives of the gentry to tell romance set during the regency. It does mean that you end up with a lot of "I showed up for the romance but now I'm here for the history of women making choices" and the romance feels almost secondary, but that might also be what catches my attention.
