Vocation

Andrew Tremaine's search for the secret of interstellar travel leads him into a world where genius, power, and restraint are inseparable. At a glittering ballroom gathering, the magnetic Gerd and Gaya Lel Rayne dazzle everyone around them, while Andrew's suspicions deepen after his psychologist friend Gene Leglen finds no clear proof of abnormal minds. What if humanity is being held back by an invisible limit, and the Raynes know more than they admit? As Andrew presses the issue, Gene helps him pursue a dangerous theory: that humans may use only a fraction of their brains, and that some unseen force could be suppressing their true potential. Their covert investigation escalates when Gene's thought-amplifying machine begins to push his mind beyond ordinary bounds, and Andrew is drawn into the field himself, awakening to overwhelming sensory and mental power. Yet the greater his understanding becomes, the more he senses the cost of such knowledge. Confronting Gerd directly, Andrew learns that Terra is being denied stellar power not out of cruelty, but caution. The aliens believe humanity is not ready for technologies that could become catastrophic in reckless hands. Beneath the mystery lies a tense struggle between ambition and responsibility, and between a younger civilization's hunger to advance and the discipline required to survive its own success.
