Star Wars® : Rebel Force #6

It was supposed to be a simple mission to the palace of Nyemari. Quick, covert, easy. But before the Rebels can get off the planet, Luke receives a mysterious—and deadly—message from former Imperial Commander Rezi Soresh. Though Soresh's assassin, X-7, didn't manage to kill Luke, Soresh hasn't given up on vengeance. Luke must surrender himself, or Soresh is prepared to kill a ship full of innocent travelers. Luke has no choice. To save the hostages, he must follow Soresh's directions. Even if they lead straight into a trap.
