Good, Deep, Fantasy/Sci-Fi Series (for Older Readers)

[Benholio]

Glad to see Guy Gavriel Kay got some mentions. I almost listed Tigana and Lions of Al-Rassan in my first reply, but I was in a hurry and kept it brief.

I am not one to re-read many books. As a matter of fact, I could probably count the number of books I've read twice on one hand, if I could remember them. I think I will go back and re-read Tigana and Lions now, though, thanks to this thread.
