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.

It is a golden age. Intrepid hyperspace scouts expand the reach of the Republic to the furthest stars, worlds flourish under the benevolent leadership of the Senate, and peace reigns, enforced by the wisdom and strength of the renowned order of Force users known as the Jedi. With the Jedi at the height of their power, the free citizens of the galaxy are confident in their ability to weather any storm But the even brightest light can cast a shadow, and some storms defy any preparation.

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.

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.
