Publisher's summary
All spacelanes lead to Boonda the Hutt's palace! From one direction comes Olag Greck, looking to strike a shady deal, and from the other comes a drone barge loaded to the gunwales with angry droids, among them a mysteriously transformed See-Threepio.

He's undergone a drastic change of personality and become a charismatic leader of the droid rebellion. But the cavernous halls of Boonda's palace hold surprises for everyone, and as with all Hutt palaces, not everyone who enters gets out alive!
