Star Wars: Darth Vader - Dark Lord of the Sith Vol. 3: Burning Seas
As the Empire's grip tightens on the galaxy, the stirrings of a rebellion begin in the Mon Cala system. The fearsome Darth Vader knows order must be maintained at all costs - and this time the job of snuffing out hope falls to Vader, his Inquisitors...and Wilhuff Tarkin! Bringing Mon Cala to heel means finding the surviving Jedi that foment this unrest. No tolerance for rebellion can be afforded. But how far will Vader go to complete his mission? When the Dark Lord of the Sith and his Inquisitors finally track down their targets, a resistance will crumble and the seas will weep. And when the time comes for Tarkin to repay a long-standing debt to Vader, settling what is owed will require every last bit of his cunning - and will cost more than he ever imagined!
