Belonging to the larger collection of works known as The New Jedi Order, is the Force Heretic trilogy.
This trilogy was authored by Sean Williams together with Shane Dix, and it saw publication under the Del Rey imprint in 2003. Uniquely, it stands as the sole trilogy within the New Jedi Order series, which is otherwise characterized by duologies and individual novels.
The Science Fiction Book Club put out an omnibus edition in hardcover that contained the entire trilogy.
'The Yuuzhan Vong, moving with speed and lethal force, have cut a swath through the New Republic—and are now poised to achieve total dominance. However, some brave individuals still dare to stand against them…'
Emerging from the ruins of the New Republic—shattered by the brutal Yuuzhan Vong onslaught—the newly established Galactic Federation of Free Alliances has emerged, dedicated to restoring galactic peace. First, however, the Yuuzhan Vong must be contained once and for all. While Han and Leia Solo embark on a journey to mend the fracturing galaxy, Luke Skywalker seeks a world shrouded in legend: Zonama Sekot, a sentient planet rumored to have successfully defended itself against a Yuuzhan Vong invasion decades prior. Unlocking the mysterious secrets of Zonama Sekot could potentially shift the balance in this relentless war.
Aboard the Jade Shadow, Luke, accompanied by his wife Mara, Jacen Solo, and fellow Jedi, venture into the Unknown Regions. This area, teeming with hostile cultures and outright adversaries, is where clues suggest the elusive planet might be located. Yet, their mission is barely underway when the search party stumbles upon a devastating battle. An Imperial Remnant, retreating from the overwhelming Yuuzhan Vong, is on the verge of annihilation. It would appear that those aboard the Jade Shadow have no choice but to abandon the Empire to its inevitable fate.
But these are Jedi, not just ordinary space travelers…
