BIG DAMN SPOILERS So when I was being vague about Mara Jades murderer? Yeah, it was her nephew Jacen Solo. It took over a full book for the rest of the family to discover this, at which point it became clear to them all that Jacen was beyond redemption. For complicated reasons, it was Jacens twin Jaina who took it upon herself to kill Jacen before he succeeded in taking over the galaxy. Their fight, while not as good as it would have been if Matthew Stover wrote it, is still suitably epic. And when Jaina wins, it has all the great elements of a bittersweet victory.
