Bow down, motherfu*kers. The Queen is in the house.
Go look at my list of books by author. Note that one author has TWENTY-THREE entries on it. Lisa Kleypas is my historical romance genre gold standard. Hers are the books I place on the “keeper shelf”, have re-read the most, and will recommend to anyone who will listen. As is my wont, I read one of her best books first and then went back and devoured everything else I could find. Her earliest work is a bit rough, but she started gathering steam with Dreaming of You (CLASSIC) and forged ahead from there. She has a few connected series, but The Wallflowers and The Hathaways are the strongest.
Kleypas specializes in rakish, sardonic, self-made men, otherwise known as my catnip. One of the things I find particularly enjoyable is that the men have either worked their way up from virtually nothing, or are making their own way in the world despite inherited privilege.
The Wallflowers, Annabelle, Evie, Lillian, and Daisy, are four young women out in society who bond over their mutual rejection by eligible men. After spending time on the side lines of many a ballroom, they decide to work together to find suitable husbands. There is a lot of cross-pollination between the stories which means you get to visit the characters multiple times.
