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.

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.

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.

From the ashes of the New Republic, torn to shreds by the savage Yuuzhan Vong forces, the newly formed Galactic Alliance has risen, determined to bring peace to the entire galaxy. But first the Yuuzhan Vong must be contained once and for all. And so Luke Skywalker seeks a world long lost to legend: Zonama Sekot, a sentient planet believed to have repelled an invasion by the Yuuzhan Vong decades ago. Deciphering the enigmatic secrets of Zonama Sekot just might turn the tides of a relentless war.

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.

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.

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.

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.

Six Jedi Masters, 12 Jedi Knights, and 50,000 men, women, and children, will embark - aboard a gargantuan vessel, equipped for years of travel - on a mission to contact intelligent life and colonize undiscovered worlds beyond the known galaxy. The government bureaucracy threatens to scuttle the expedition before it can even start - until Master C’baoth foils a murderous conspiracy plot, winning him the political capital he needs to set in motion the dream of Outbound Flight.
