No, not Robin Hobb, that was Fool's.. something else. The Liveship Traders, the Farseer Trilogy, and the Tawny Man, that was it. That trilogy was called the Tawny man.
I can see how you could make that mistake, but the Fools Gold refers to iron pyrite, not Beloved. The last book was called the Rose of the World. I don't remember any other names, but I remember the story.
