Grif Vindh, Captain of the Fool's Errand, just pulled off the job of a lifetime: against all odds, he and his crew smuggled a rare anti-aging drug out of Ur Voys, one of the most secretive and secure facilities in the Empire of the Radiant Throne. It was every smuggler's dream, the "Big Score," and they find themselves filthy rich as a result.
But their good fortune attracts exactly the wrong kind of attention: the Alliance of Free Worlds has been trying to infiltrate Ur Voys without success, so they conscript the only man who has: Grif Vindh. The Radiant Throne, desperate to know how their security was so easily thwarted, send one of their best to track him down and learn the truth… by any means necessary. Grif and his crew must perform the impossible a second time: break into Ur Voys, steal something so secretive their employers don't really know what it is, and get away clean.
Along the way they'll have to deal with deadly spies, psychotic telepaths, vicious cyborgs, inconvenient family ties… and a hyperintelligent bug who always bets against its captain.
