Allegiance (novel)

Allegiance is a book by Timothy Zahn, set directly after the ending of A New Hope. Luke Skywalker, Princess Leia, Han Solo, Chewbacca, and Mara Jade are to be the main characters, with Darth Vader making only a minor appearance. As the title would suggest, the book's subject will be, according to Zahn, "...three different people and groups with allegiance issues."
