Star Wars - Shadows of the Empire

His name is Xizor, Underlord of a galaxywide criminal organization called Black Sun. He seeks to displace Darth Vader as Emperor Palpatine's right hand. To do so, he will hatch a brilliantly evil plan to discredit Vader in the Emperor's eyes. But in the meantime he will join the Dark Lord in an unholy alliance whose common target is the young Rebel hero, Luke Skywalker.

While Vader and Xizor bait their trap for Luke, Han Solo is being held captive, flash-frozen in a carbonite slab. Mourning the loss of the man she loves, Princess Leia mounts a rescue mission to free Han. She enlists the aid of Luke, who is sharpening his skill in the Force at Ben Kenobi's home on the edge of Tatooine's Western Dune Sea. Skywalker organizes a crack fighting force, including Wedge Antilles and his famous X-wing squadron; Lando Calrissian; and the mercenary Dash Rendar. Yet the fierce battle that ensues to rescue Han will not go according to plan. For the Empire's spies are everywhere.
