tl;dr Books, most likely generated by an LLM, were being sold on Amazon under Jane Friedman’s name. The same books were added to her Goodreads profile. Amazon initially refused to remove the books. If it’s happening to her, it’s definitely happening to other authors.
I follow Mercury Stardust (aka the Trans Handy Ma’am) on TikTok. She has a book coming out at the end of the month, but she had someone steal her name and the book title and start selling a book filled with utter nonsense. It apparently took forever for them to take the copycat down.
