"In the wake of the scourge of the droids that threatened the Rebellion and the Empire, Vader explores his powers and takes on the most dangerous team of rebel heroes he's ever faced! Meanwhile, the greatest threat to the Emperor's rule is rising--from within the Empire itself! Will the Dark Lord quell this insurrection...or join it? Palpatine's aide and a double agent, the Umbaran Sly Moore nutures her conspirators! Kitster and Wald return--along with the death machinery of Governor Tauntaza! But when a group of betrayers comes together, how long will it be before they turn on one another? It all leads up to the assault on the home of the Emperor's greatest secrets and treasures! Plus: a rebel squad of cyborgs brings chaos, meet Vader's new enforcers, and what treasure or horror lies within the Martyrium of Frozen Tears? And Sabé joins the hunt for Luke Skywalker!" -- Back cover.
