Taken from the cover flap of the novel VANDALS OF THE VOID by Jack Vance:
The only thing teen-age Dick Murdock knew about space piracy was what he read in the papers - until he flew from Venus to join his father at the Moon's observatory. During that flight he saw a sample of what pirates could do - even in 1985. For along the trans-space orbits that connected Mother Earth with its colonies on Mars and Venus hung the lifeless hulk of a spaceship blasted and looted by interplanetary bandits.
Around this theme Jack Vance weaves a thrillingly realistic novel that features a quick-witted and courageous teen-ager. Dick Murdock was fascinated by the observatory that his father headed, but he was more interested in the mysterious actions of the men who worked there. His prospecting trips on the Moon aboard a homemade raft with Crazy Sam, the aged, space-happy caretaker of the abandoned Security Station; Dick's slow realization that accidents at the observatory are not always accidents, and his stealthy investigation of what goes on under the surface of the Moon builds to a taut and breath-taking climax that explodes when U N interplanetary authorities appear on the scene.
A tale of mystery and excitement; a convincing narrative of personal daring and courage against limitless odds, VANDALS OF THE VOID will grip any reader's attention till the last battle fires die above the frightenend earth colony on the planet Venus!
