Repercussions from the dark side’s fatal seduction of Jacen Solo and the mysterious plague of madness afflicting young Jedi continue to wreak galaxywide havoc. Luke and Ben Skywalker are in pursuit of the now Masterless Sith apprentice—a chase that leads to the forbidding planet Dathomir, where the Skywalkers will be forced into combat for their quarry and their lives. Meanwhile, Han and Leia have completed their own desperate mission, shuttling madness-stricken Jedi to safe haven beyond the grasp of Galactic Alliance Chief of State Natasi Daala. Yet no greater threat exists than Abeloth, a being of ravenous dark-side energy who calls out to Jedi and Sith alike. For some it may be the ultimate source of answers for survival. For others it could be the ultimate weapon of conquest. But for all, it is a game-changing encounter of untold magnitude with unimaginable consequences.
