Backlash
(Book)

Repercussions from the dark side's seduction of Jacen Solo and the plague of madness afflicting Jedi wreak havoc. Having escaped the Mind Wakers and a Sith hit squad, Luke and Ben Skywalker are in pursuit of the now Masterless Sith apprentice. It leads to Dathomir, where dark-side Force-wielders give Vestara the edge to escape and where the Skywalkers will be forced into combat. Han and Leia Solo completed their mission, shuttling madness-stricken Jedi from Coruscant to safe haven beyond the grasp of Galactic Alliance Chief of State Natasi Daala, who is determined to shatter Jedi Order resistance. A being of dark-side energy named Abeloth calls out to Jedi and Sith. For some it may be answers. For others it could be a weapon. For all, it is a game-changing encounter and a gambit with consequences.,- From inside cover.
