Timothy Zahn's bestselling Thrawn trilogy (1991–1993) reignited interest in the franchise and introduced the popular characters Grand Admiral Thrawn, Mara Jade, Talon Karrde, and Gilad Pellaeon. The first novel, Heir to the Empire, reached #1 on the New York Times Best Seller list, and the series finds Luke, Leia, and Han facing off against tactical genius Thrawn, who is plotting to retake the galaxy for the Empire. In The Courtship of Princess Leia (1994) by Dave Wolverton, set immediately before the Thrawn trilogy, Leia considers an advantageous political marriage to Prince Isolder of the planet Hapes, but she and Han ultimately marry.
