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.

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.

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.

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.

The brutal Yuuzhan Vong are scouring the universe for Jedi to slaughter. With no help from the divided New Republic, the Jedi stand alone against their seemingly invincible foe. Han and Leia Organa Solo risk deadly consequences with their controversial tactics to bolster the Jedi resistance. And after uncovering a new Yuuzhan Vong menace, Anakin and Tahiri find themselves wanted for murder by the Peace Brigade. To avoid capture, they jump into hyperspace - and into far graver trouble.
