In your serial books, before you write the first one, do you sketch or outline the entire story? I am thinking in particular of the Viking series. I recall a fair amount of foreshadowing, eg. Gesiela's comment concerning what her children will grow to be.

An outline? No, I don't. I have a very broad idea of where I want the book to go, then just let the characters sort it out amongst themselves. I'm not saying this is the right way to do it - some writers plot very carefully, and their books are great, but others, like me, leave it to instinct.
