What with discussion of a D&D movie, I've just seen this on Quora
Mercedes R. Lackey on Quora said:Disney recently dumped every single one of their book lines that wasn’t in an already-popular movie francise. My books were part of that. My agent told me that they have no intention of publishing any more books that are not tied in to movies and cartoons. And they got rid of all of the authors and the books they had previously published that had not generated any movies. Every single one. Hundreds of books, and dozens of authors.
