For those of you who have never read 'Sacrifice', or those of you who have forgotten, here's a quick re-cap:
Previously in Sacrifice...
The journey began with Sith Lord Jacen Solo, his Dark Apprentice Tahiri Veila at his side, attempting to put an end to the long-raging civil war between the Galactic Alliance and the Corellian insurgents.
At first, things were going well for Solo and his soldiers; the rebels were falling, and victory seemed to be within his grasp. Unfortunately for him, he'd put his trust in the wrong person. Ben Skywalker had betrayed him, and waiting just beyond the borders of hyperspace was a trap even the mastery of a Sith Lord couldn't break.
The Galactic Alliance was losing, and Tahiri's allegiance was wavering. In a desperate move, Jacen confronted his apprentice and his parents, killing them all in a fit of uncontrollable rage. Revolted by what he had done, Jacen clutched at the last of Tahiri's life, vowing to make things right and stop the evil transformation that had destroyed a galaxy.
With that promise in mind, a cleansed Jacen Solo returned to the point his dark path had begun, taking a flow walk back to Myrkr, with an older Tahiri at his side once more. From this, they were able to transfer some of the older Tahiri's memories to her younger counterpart, leaving her to guide the young Jacen to a sacrifice he should have always made.
Now knowing the outcome of the Myrkr mission, the young Tahiri pushed the strike team in a different direction, and subsequently took the amphistaff wound to the abdomen that was meant for her boyfriend, Anakin.
The battle meld fell into disarray; the darkness was everywhere, and their trust in each other had long since evaporated. Tahiri's meddling with the mission had resulted in more deaths than before, and more unease than she'd ever thought possible.
On top of everything else, Jacen Solo's darkside descent had started early, and Tahiri's trust in him crumbled until it was nonexistent. His choice already made up, Jacen continued on with his plan, plunging head on into the jaws of the voxyn queen and sacrificing himself for the survival of his siblings, his parents, and the galaxy.
Jacen's sacrifice did not come without a price. His siblings, enraged with grief and loss, left the strike team behind to make a last ditch-effort to save his life. This rash decision sealed their fate, and together, Jaina and Anakin dove into a swarm of Yuuzhan Vong warriors, determined to go down fighting, just like their brother.
The remaining members of the strike team, now in the control of the decoy leader, Ganner Rhysode, took the battered Tachyon Flier and left the Myrkr system, leaving behind perhaps the galaxy's greatest hope since Luke Skywalker himself.
