Star Wars, the clone wars. The Wind Raiders of Taloraan
(Book)

Duty takes Padawan Ahsoka Tano, her master Anakin Skywalker, and Obi-Wan Kenobi to the gas planet Taloraan, only it's not the kind of duty Ahsoko enjoys. They've come to negotiate a treaty with the technology-embracing Defrandi, which promises many long diplomatic discussions. But when Ahsoko alone uncovers a Separatist plot, she must seek assistance from the primitive, beast-riding Wind Raiders to denounce the Defrandi and save the lives of Anakin, Obi-Wan and herself.
