I only read genre fiction and none of these author names are familiar to me. I usually read about people of modest means or people with genuine problems, not upper-middle class privileged elites whose "sadness" relates mostly to their shallowness. Even though women's fiction titles about those women are popular, I don't read or write those.
A standard setup for a genre contemporary romance today is the young woman who has been done out of a deserved promotion and/or fired from her big city job, come home to her apartment to find her fiance having sex with her best friend, and now has nothing and must retreat to the small town of her birth. Meh, but that's a version of sadness that may reflect some of women's genuine frustrations with our current society.
A number of genre contemporary romances and romcom romances start with the heroine making a complete fool of herself. That includes the newly big trope of having a one night stand with a guy who turns out to be her boss, a fender bender involving bad language with a guy who turns out to be her boss, a _____ with a guy who turns out to be her boss, etc. A different kind of oops are the stories in which the young woman literally trips and falls, of course scattering embarrassingly personal items all over an airport or city sidewalk. Sigh. When that happens, I shut the book and delete it from my Kindle. In real life, in a crowded setting, how often has any of us ever seen someone take that kind of pratfall? I'm trying to think of even one time while I lived in NYC. And if it did happen, it happened to an elderly woman or man. Granted, today's young women often wear sky-high heels and platforms, too, but that's no excuse for the overly klutzy characterization of a heroine. Not interested.
