I forgot the title of the book but I remember one scene.
It goes like the heroine went to a party with the hero and the hero’s ex-mistress was there. The mistress slapped the heroine and the heroine slapped her back.
It seemed like an abandoned wife/marriage of convenience troupe. Probably a regency historical romance.
Maryse: I’m going to post something super silly that my boyfriend said when I read this question to him (’cause I loved the description of the scene so I just had to read it to him). So…. this is “the first guess” (albeit obviously wrong). LOL!!
