I think I read these books by Georgette Heyer are called Regency romances, but whatever they're called, I like them! They're historical fiction set in the late 1800s in England and they're fairly formulaic, but for audiobooks, I like that because then I don't have to think too much, and that's a good thing because I usually listen when I'm driving. So far I have listened to three of them and am on my fourth. They have fantastic character development and women characters who were quite spunky for their time because they always have their own ideas and aren't afraid to say them (or sometimes act on them without saying anything).
If you like historical fiction and enjoy stories treat move at a gentle pace, give Georgette Heyer a try!
