Star Wars: The Jedi Academy Trilogy, Volume 2: Dark Apprentice

While Luke Skywalker takes the first step toward setting up an academy to train a new order of Jedi Knights, Han Solo and Chewbacca are taken prisoner on the planet Kessel and forced to work in the fathomless depths of a spice mine. But when Han and Chewie break away, they flee to a secret Imperial research laboratory surrounded by a cluster of black holes - going from one danger to a far greater one.

Luke Skywalker and Han Solo, cloaked by the Force and riding with the hostile Sand People, have returned to the dunes of the desert planet Tatooine in hopes of finding what Luke so desperately seeks: contact with Obi-Wan Kenobi. Luke is hoping the old Jedi Knight's spirit will tell him how to help his love, Callista, regain her lost ability to use the Force.

On the planet Tython, the ancient Je’daii order was founded. And at the feet of its wise Masters, Lanoree Brock learned the mysteries and methods of the Force - and found her calling as one of its most powerful disciples. But as strongly as the Force flowed within Lanoree and her parents, it remained absent in her brother, who grew to despise and shun the Je’daii, and whose training in its ancient ways ended in tragedy. Now, from her solitary life as a Ranger keeping order across the galaxy, Lanoree has been summoned by the Je’daii Council on a matter of utmost urgency.

Luke Skywalker is worried: A handful of Jedi Knights, including his nephew and niece, Jaina and Jacen Solo, have disappeared into the Unknown Regions in response to a strange cry for help that only they could hear. Now the alien Chiss have angrily lodged a formal complaint, accusing the missing Jedi of meddling in a border dispute between the Chiss and an unidentified aggressor.

It is a time of tranquility for the New Republic. But the peace is short-lived. Luke must journey to his mother's homeworld in a desperate and dangerous quest to find her people. An adventurous Lando must seize a mysterious spacecraft that has weapons of enormous destructive power. And Leia, a living symbol of the New Republic's triumph, must face down a ruthless leader of the Duskhan League, an arrogant Yevetha who seems bent on a genocidal war.
