For example, Grace Burrowes is a mess, historically speaking. I do NOT like her snippy/snappy style of writing and very often, I am really turned off by her attempts to work modern day issues into historical contexts. But a few of her books really have great stories and one gets the impression that she is getting this storyline from somewhere not inside herself even if she gives it her "riff on life" treatment.
Well, being a non-English speaker, I actually appreciate a more "simple" language and don't mind that they don't talk in a more "sophisticated" manner. In fact, "The Dukes Disaster" by Grace Burrowes is the hardest to understand so far. And it is quite annoying at times. And I am actually reading it out loud, and still often don't get it! This book is probably a solid proof that my English still requires a lot of improvement.
As for Bridgerton series, right now on a second audiobook ("The Viscount who loved me"), and it is a charming enough story. Rosalyn Landor's narration does make it very entertaining.
