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.

The alien Yuuzhan Vong have launched an attack on the worlds of the Outer Rim. They are merciless and they stand utterly outside the Force. Even the Jedi are rendered helpless by this impervious foe, and their solidarity has begun to unravel. While Luke struggles to keep the Jedi together, Knights Jacen Solo and Corran Horn set off on a reconnaissance mission to the planet Garqi. There they uncover a secret that might be used to undermine the enemy - if only they can stay alive long enough to use it!

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.

Leia Organa Solo, estranged from her husband, Han, oversees the evacuation of refugees on planets in the path of the merciless Yuuzhan Vong. Luke Skywalker struggles to hold the fractious Jedi Knights together, even while one of them undertakes a bold but reckless undercover mission. And Han Solo stumbles into the dark heart of a raging battle.

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.

Han Solo and Leia Organa Solo work to help refugees flooding in to the planet Duro from the Rim worlds. However the dreaded Yuuzhan Vong have chosen Duro as their next target. Jacen Solo, working at his father's side, finds himself on the horns of a dilemma: how to reconcile using the Force as a tool for good, yet still fight the evil invaders. He must make the right choice, for the future of his family, and possibly of the New Republic itself, hangs in the balance.

It is a solemn time for the New Republic, as the merciless Yuuzhan Vong continue their campaign of destruction. The brutal enemy has unleashed a savage creature capable of finding and killing Jedi Knights. And now Leia Organa Solo faces a terrible ultimatum. If the location of the secret Jedi base is not revealed within one week, the Yuuzhan Vong will blast millions of refugee ships into oblivion.

With the enemy in hot pursuit, Jaina Solo is forced to seek haven in the unfriendly Hapes Cluster, where the Jedi are held responsible for a past tragedy - and where the royal family has grim plans for their famous Jedi guest. Even more sinister are the intentions of the Yuuvhan Vong, desperate to capture Jaina for a hideous sacrifice. Grief-stricken and obsessed with revenge, Jaina is blind to these threats and to the overpowering evil dangerously close to consuming her.

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.

Rife with hostile cultures and outright enemies, the Unknown Regions hold many perils for Luke Skywalker and the Jedi, who are searching for Zonama Sekot - the living planet that may hold the key to dealing once and for all with the Yuuzhan Vong.

Scattering after the Yuuzhan Vong's invasion of Coruscant, the panic-stricken members of the New Republic Advisory Council pause just long enough to set up a mock defense on nearby Borleias and attempt to buy time - which fools no one, least of all the Jedi. Bearing down swiftly on Borleias is a Yuuzhan Vong invasion fleet, determined to destroy the galaxy's remaining defenders.

The Empire's master plan is under way. The New Republic is on the verge of civil war and the rumor that the legendary Admiral Thrawn has returned from the dead is rallying the Imperial forces. Now Luke Skywalker, Han Solo, Princess Leia, and their allies face the challenge of their lives. They must infiltrate a hidden fortress filled with Imperial fanatics, rendezvous with a double-dealing Imperial commander, and journey into enemy territory to learn the identity of those responsible for an act of unthinkable genocide. But most important of all is the truth about Thrawn.

Luke Skywalker's daring mission to halt the Yuuzhan Vong's nefarious plot to overthrow the New Republic is struggling on all fronts. And time is slipping away for Han and Leia Organa Solo, trapped on a small planet whose rulers are about to yield to Yuuzhan Vong pressure to give up the Jedi rebels.

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.

The Galactic Alliance's hard-won success in countering the Yuuzhan Vong onslaught has proven all too brief, and the tide has turned once more to the invaders' advantage. Having overcome the sabotage strategies of the Jedi and their allies, the marauding aliens have pushed deeper into the galaxy and subjugated more worlds in their ruthless quest for domination.
