I haven’t proved your point exactly, or even vaguely. Your assertion - that she was somehow forced into writing more books than she was ready for by a sudden passionate fanbase - is simply incorrect. She chose to accept a contract that obliged her to turn her single book into a trilogy.

I don’t know why “of course they’re not great, she’s a new writer”. Plenty of new writers and first novels are amazing. And it wasn’t a case of readers demanding a trilogy, she signed a lucrative publishing deal to write a trilogy on the strength of the first book. She didn’t stumble into it, she wanted to be an author and managed it. She just managed it with work that is generally held to be low quality. Stuff of nightmares? Come on, now :)

Asimov had a great spin on that called “The Ugly Little Boy”. I really felt the ending.
