Xenon's Seventh Circle

I read the first eight or so of the Riftwar books when I was the kind of age that kind of book is aimed at. If memory serves, the Krondor's Sons duology - "Prince of the Blood" and "The King's Buccaneer" - is a lot of fun. It has one of my favourite ever fictional characters: Nakor the Isalani, the magician who insists that there is no such thing as magic, and whose signature trick is producing a seemingly endless progression of oranges out of an empty bag.
