The Viscount Who Loved Me by Julia Quinn

This is straight ahead romance novel stuff, made more pervasively known because of the Netflix mini-series that now has four seasons, and likely more to come. The book hews close to the series, with some more believable progression of the relationship between Kate and Anthony. The advantage of the book is that there is a view into the character's inner thoughts and that is missing when it comes to the big screen. The one interesting given in this time period compared to 200 years later, which is where we are, this is set in the time of Jane Austen, a hundred years before the onset of WWI, is that the expectation that one would marry for love is very low. Women marry for financial security, for them and their families, and men have dalliances and marry for duty (and maybe keep up with the dalliances). The idea that there would be joy or love involved is secondary, and when that is the baseline, it is no wonder there is little in the way of happiness to be found. The Bridgertons break that mold and are better for it (of course, they are also rich).
