Five intergalactic criminal masterminds raid the tranquil world of Mount Pleasant, leaving behind only ruin and slaughter—and the orphaned child Kirth Gersen, who comes to manhood swearing to take bloody revenge. Now Gersen roams the galaxy, bringing vengeance to the Demon Princes one by one, in Jack Vance's classic series of hardboiled space opera.

In a seedy tavern on Smade's Planet, Kirth Gersen picks up the trail of Attel Malagate, a member of an alien species called Star Kings, who masquerade as humans. Malagate maintains anonymity behind a screen of sinister henchmen, but Gersen will combine subtle guile and stark violence in a strategy to bring him face to face with the first of the Demon Princes.
