THE END OF ETERNITY

Time theories set the story of Technician Harlan's journeys upwhen and down-when until he meets Noys Lambent who cracks his observer's objectivity. She causes him to plot a crime against Eternity to keep her with him which brings him up against the secret of his training and his part in the time pattern. It is she who goes with him to Primitive times -- and persuades him against neurotic world governance for the future of Earth. Combinations and permutations by the dozen.
