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.

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.

As the Jedi and the Republic focus on internal struggles, a new threat surfaces beyond the farthest reaches of the Outer Rim. An enemy appears from outside known space, bearing weapons and technology unlike anything New Republic scientists have ever seen. Suddenly, Luke, Mara, Leia, Han Solo, and Chewbacca, along with their children, are thrust again into battle. But this time, all their courage, sacrifice, and even the power of the Force itself, may not be enough.

The Empire stands at the brink of total collapse. But they have saved their most heinous plan for last. First a plot is hatched that could destroy the New Republic in a bloodbath of genocide and civil war. Then comes the shocking news that Grand Admiral Thrawn--the most cunning and ruthless warlord in history--has apparently returned from the dead to lead the Empire to a long-prophesied victory.

It is a perilous time for the New Republic. Just when unity is needed most, mistrust is on the rise. Even the Jedi feel the strain, as rogue elements rebel against Luke's leadership. When alien invaders known as the Yunnan Vong strike without warning, the New Republic is thrown on the defensive. Merciless warriors, the Yunnan Vong glory in torture. Their technology is as strange as it is deadly. Most ominous of all, they are impervious to the Force.
