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 an age of exploration. Jedi travel the galaxy, expanding their understanding of the Force and all the worlds and beings connected by it. Meanwhile, the Republic, led by its two chancellors, works to unite worlds in an ever-growing community among near and distant stars. On the close-orbiting planets of Eiram and E’ronoh, the growing pains of a galaxy with limited resources but unlimited ambition are felt keenly. The two worlds’ hatred for each other has fueled half a decade of escalating conflict and now threatens to consume surrounding systems.

Once the Sith order teemed with followers. But their rivalries divided them in endless battles for supremacy - until one dark lord at last united the Sith in the quest to enslave the galaxy and exterminate the Jedi. Yet it would fall to another, far more powerful than the entire Brotherhood of Darkness, to ultimately realize the full potential of the Sith, and wield the awesome power of the dark side as never before.

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.

Heir to the Empire begins five years after Return of the Jedi. The Rebel Alliance has destroyed the Death Star, defeated Darth Vader and the Emperor, and driven the remnants of the old Imperial Starfleet back into a quarter of the territory it once controlled. But thousands of light-years away, the last of the Emperor's warlords have taken command of the remains of the Imperial fleet - and have made two vital discoveries that could destroy the fragile new Republic.
