Star Quest: Terrorsaur!
by Terrance Dicks (W. H. Allen, 1981)
Dicks concludes his Star Quest trilogy with a fast-moving but inconsequential adventure. The young protagonists are reunited with their friends from the first book and defeat the same enemies—hapless space supremacists—thanks to some guff about a possibly sentient planet-wide ecology.
Star Quest: Roboworld
by Terrance Dicks (W. H. Allen, 1979)
Dicks once again borrowed heavily from 1970s Doctor Who in scripting this middle-grade adventure of human outcasts, robot sentience, deranged scientists and plucky rebellion. This second book in the trilogy is more assured than the first, though never reaching any great heights.
Star Quest: Spacejack!
by Terrance Dicks (W. H. Allen, 1978)
Drawing on the SF zeitgeist of the late 1970s, Dicks managed to channel Doctor Who, Star Wars, and even Planet of the Apes in this slim Middle Grade adventure. An easy, fast-paced read with decent characterisation and several positive (if overt) morals.
