Hostage
(Book)

The deadly assassin contracted by the Empire, X-7, is closer than ever to discovering the identity of his target. He's already infiltrated the top levels of the Rebel Alliance and gained Princess Leia's trust but he still hasn't been able to get Leia to give up the classified information he desperately needs. After all, Leia Organa is unbreakable: the youngest, toughest member of the Galactic Senate, and, since its dissolution, the fiercest opponent of the Empire. She's survived kidnapping and torture under Darth Vader, but she's never had to do anything more difficult than her latest mission. She is going home and X-7 knows it will be the perfect opportunity to destroy her.
