It's about an author who hasn't managed to come up with one decent idea in ten years, and so her publisher and agent encourage her to write more books in her most lucrative franchise in order to make more money. The author sells out and writes it because she's bereft of any new ideas. Unfortunately, none of her books except for the first were actually very good because her world building ability sucks and makes zero sense when examined with even the most remote amount of scrutiny.
