I know (or, perhaps I should say that I've subsequently figured this out!), Shing, but I picked up Fool's Errand at a library sale for 50 cents, and one page led to another, and....well, you get the picture!
So, having finished Fool's Errand (and it really wasn't too hard to pick things up, although I'm sure I'd have a deeper understanding of some of the characters had I gone sequential) do I a) go back and read the Farseer triology before proceeding any further, or b) finish the Tawny Man series and try to see the two stories as separate entities when I go back for Farseer?
