Children of the Jedi introduces Callista, a Jedi warrior of long ago who gave her life to foil one of the Empire's darkest plans, a plot to destroy a sanctuary for the families of Jedi knights. The plot involved a dreadnaught, one of the Empire's most devious inventions. Crippled during the war against the Empire, the vessel has drifted through space for years. But now it is slowly reactivating and resuming its inexorable mission. And only Luke Skywalker can feel its evil presence.

Nam Chorios is a barren backwater planet that was once a dreaded prison colony and is now home to a fanatical religious cult. It is here that Princess Leia has been taken captive by a ruthless warlord. Meanwhile, Luke lands on a mysterious planet in search of his lost love, Callista, only to discover the Force is his own worst enemy. But worst of all, as Han, Chewie, and Lando leave Coruscant on a desperate rescue mission, a malevolent life-form, unlike any the galaxy has ever seen, awakens.

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.

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.

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.
