Star Wars: The New Jedi Order: Agents of Chaos (abridged)

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.
