Star Wars: Scourge by Jeff Grubb
When news of the death of his former apprentice reaches Jedi Master Mander Zuma, he is immediately suspicious. Toro Irana was on the trail of something big when he died--something involving a mysterious new drug. As the Jedi Master investigates further, he finds himself deeply involved in the political machinations of the Hutts, dealing with the sister of the deceased's desire for revenge, and the growing realization that there's more to being a Jedi than training and studying. A fun and exciting paperback original by Jeff Grubb.
