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.

No longer content with the destruction the Yuuzhan Vong have already sown, Warmaster Tsavong Lah has demanded the heads of all the Jedi. The Jedi Knights are in terrible danger, and none more so than the young students at the Jedi academy on Yavin 4. Impatient, and figuring that forgiveness is easier to come by than permission, Anakin Solo takes off for Yavin 4 in his X-wing.

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.

Merciless attacks by an invincible alien force have left the New Republic reeling. Dozens of worlds have succumbed to occupation or annihilation, and even the Jedi Knights have tasted defeat. In these darkest of times, the noble Chewbacca is laid to rest, having died as heroically as he lived. A grief-stricken Han Solo is left to fit the pieces of his shattered soul back together before he loses everything: friends, family, and faith.

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.

The next chapter in the extraordinary history of the star Wars galaxy begins here...After a violent civil war and the devastation wrought by the now-fallen Darth Caedus, the Galactic Alliance is in crisis - and in need. From all corners, politicians, power brokers, and military leaders converge on Coruscant for a crucial summit to restore order, negotiate differences, and determine the future of their unified worlds. But even more critical, and far more uncertain, is the future of the Jedi.

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.

After years of waiting in the shadows, Darth Sidious is taking the first step in his master plan to bring the Republic to its knees. Key to his scheme are the Neimoidians of the Trade Federation. Then one of his Neimoidian contacts disappears, and Sidious does not need his Force-honed instincts to suspect betrayal. He orders his apprentice, Darth Maul, to hunt the traitor down.

The overthrow of the Republic is complete. The Separatist forces have been smashed, the Jedi Council nearly decimated, and the rest of the Order all but destroyed. Now absolute power rests in the iron fist of Darth Sidious - the cunning Sith Lord better known as the former Senator, now Emperor, Palpatine. But more remains to be done.
