Dear Danielle Steel,
You are no longer allowed to write fat/curvy/robust characters again. In this book you went with the "jolly fat person" trope who also was partnered with another "jolly fat person", because goodness knows that fat people must only be partnered with one another. In your previous book Neighbors you made the fat characters downright evil and used so many negative descriptors I realized that you really must hate fat people. In The Affair, you take Athena, who could have had a very interesting storyline and you boil her down to a fat chef who doesn't have kids, who has a fat chef for a partner and they're so happy with the life they have created. All of that at face value is great, but she could have been more developed, she could have worn clothing that was described like all the slender, chic characters and not just "a flowy dress to cover her size." Your disdain for people who don't fit in your beauty standard mold is so obvious at this point. I've read every single one of your books and your fat shaming has gotten so bad it's hard to overcome it and read the book around it.
Now, that said, there are also so many other problems with this book, the ending being the obvious biggest problem. I know people change with age and the writing style of your earlier books seems to have faded. Where did the author who wrote about race in the south in the 60s (Full Circle) or about a family struggling through addiction, different points of view, and learning to accept their gay son in the 60s/70s (Family Album) go? Now you moralize so heavily it makes me wonder if you actually still live in San Francisco, one of the lost liberal cities in the country. Using "honorable, respectable, and conservative" as positive character descriptors over and over and over again surely tells your readers where your social and political leanings are. I could forgive all of that for an interesting story, or at least a well written one. Get a new editor, one who will tell you to stop repeating yourself ad nauseum.
I've only ever written one other review and that was also to ask you to do better (not that you're reading this) and remember how you used to actually write strong women. Go read your earlier books again because your female leads from Full Circle, Kaleidescape, Family Album, etc are very disappointed in you.
