Originally published in 1978, 1979, and 1981, Terrance Dicks's three Star Quest novels are now available for the first time in a single volume, with a new introduction by the author. Three young cousins get caught up in galactic events when two battling UFOs land near Stonehenge. For Jan, Kevin, and Anna it is only the beginning of their thrilling adventures. In Spacejack, the young friends meet Tell, Osar, and Garm—agents for the League, an alliance of intelligent races from across the galaxy—and come up against the Kaldor, who believe that only humans have the right to rule. Roboworld sees the cousins crashland on an asteroid infested with an army of killer robots. And in Terrorsaur!, Jan, Kevin, and Anna must search for their new friends who have gone missing while on patrol.
