Forgotten rocket

Caster was a typical city of the age. Its people were inoculated every year with U4--a drug which prevented them from asking the questions which ought to be asked. Clint Pearson had worked out a system for missing the inoculation. Only he knew that things were badly wrong. Somehow they had to make a break in the circle and think again about what a community should be like. He found allies in an outlawed, underground group. Wayne Presbon--a massive youth with the Viking spirit and two girls--Kali and Rhoda. But it was a small group to attempt to change a whole country. Until they stumbled on a piece of forgotten space age machinery. Then they could challenge the METIS--that sinister oracle which was the final power in the land. This novel, written in 1974, was never published in its original form. The work instead became used as the basis for 'Phoenix of Megaron' in the Space 1999 series.
