Another fascinating science fiction book from Isaac Asimov: His name was Andrew Harlam, he was eternal: a member of a highly exclusive organisation. He was a Technician, and his job was to range through past and present centuries, monitoring and even altering Time's myrian cause-and-effect relationships. But when he met Noys he fell victim to a pheno,enon older than Time itself - love. It was then that he realised that he must use the awesome technique of the Eternals to twist Time so that they might survive together.
