Three books into my Totally Unscientific Study, I have already found one book that is a perfect zero: Joanna Shupe’s The Lady Hellion. This is a book in which the heroine of the book was hideously slut-shamed by her asshole first lover and the hero doesn’t bat an eye when she tells him she’s not a virgin, so maybe it shouldn’t be unexpected that there’s no slut-shaming of other women, direct or indirect, but I read a lot of historical romance, so.
In fact, all three of the books in Shupe’s debut trilogy scored quite well; the average score for the trilogy was a mere 2.58, and I might have scored the first book too harshly because it was the first book in the study and I was feeling zealous.
Well done, Shupe. You were a new-to-me author, so I had no idea what to expect from you; and you used a few plotlines that tend to go along with slut-shaming-of-other-women, particularly in historicals, from which you admirably refrained. This was a very welcome surprise.
