I think there was a post recently on LKH lashouts dealing with the turning point you mentioned. Mine was BN, since I didn't think it was worth the effort to scan the book and see what's going on. The last book I thought had any value was Bloody Bones, which I think it was the last book she wrote before she divorced and hooked up with Jonboi.

I was never a big fan anyway, it's just that I found the whole situation perplexing and amusing and on the whole a great cautionary tale for any writer. Also, I've never encountered an author who destroyed her own work so thoroughly.

By the way, what is RT? "is ignorant"
