Publisher's Summary
Still convinced that Dark Jedi Asajj Ventress is alive, Obi-Wan Kenobi leads Anakin Skywalker and Senator Bail Organa to the grisly graveyard world of Boz Pity. They're hopelessly out-numbered, but Obi-Wan's obsession has made him blind to the danger.

Fortunately, help is on the way. Rig for action as Mace Windu leads a battalion of Jedi and an army of clone troopers to the rescue! All of your favorite Jedi guest star, as well as villains Count Dooku and General Grievous. Plus, the return of ARC Trooper Alpha!
