Timothy Zahn has written quite the collection of Star Wars novels. By far the creme of the crop when it comes to tie-in fiction. He has given us some great additions to the Star Wars universe as well: Talon Karrde, Mara Jade, & Grand Admiral Thrawn. His non-Star Wars fiction is pretty great as well, with some interesting moral questions thrown in for good measure.
Jaina & Jason Solo....Perfect into for Ep 7 8 & 9. The Thrawn Trilogy is set 5 years after the batter of Endor. Featuring A Empires last Grand Admiral, and all of the former crew are back in action. Its perfect for the next Episodes
