The Thrawn Trilogy boxed trilogy set includes three essential Expanded Universe books by Timothy Zahn. In "Heir to the Empire," Zahn introduces the brilliant villain Grand Admiral Thrawn, who poses a new threat to the galaxy and the beloved characters of the Original Trilogy. In the second installment, "Dark Force Rising," Zahn raises the stakes even higher, as a traitor has infiltrated the New Republic leadership, and Thrawn is on the brink of making a discovery that could end the New Republic altogether. In the final chapter, "The Last Command," Thrawn and his Imperial remnants make their final push to regain control of the galaxy, and it's up to Leia, Han, Chewbacca, and Luke to save the New Republic and confront the darkness within themselves.
