It has to be an author who is estimated to have sold at least 100 million books. There is a list of such authors here. It has to be an author who is dead, but it can't be an author whose works are in the public domain.

1.00@Shelvacu I think the way to operationalize what I was imagining is that the publisher is a publishing company that currently owns a license to print some work by the author. Is that reasonable? I don't know much about publishing or IP law.
@HarlanStewart Suppose I, right now, tell chatgpt to write ~10k words in the style of j.k. rowling and then spend a few hours on amazon to get a listing up for a print-on-demand book. The title and cover clearly advertises that it is AI generated in the style of JK Rowling. Does this market resolve yes? A "publisher" (amazon) "released" (made available as digital or print-on-demand) a novel, advertised (on the page where you can buy it) as being generated in the style of jk rowling. Amazon owns a license to print "my" work.
Ok let's add these stipulations: a retailer has to sell physical copies of the book, and it has to be generally considered to not be violating any IP law.
