Although humanity and the Overlords have peaceful relations, some believe human innovation is being suppressed and that culture is becoming stagnant. One of these groups establishes New Athens, an island colony in the middle of the Pacific Ocean devoted to the creative arts, which George and Jean Greggson join. The Overlords conceal a special interest in the Greggsons' children, Jeffrey and Jennifer Anne, and intervene to save Jeffrey's life when a tsunami strikes the island. The Overlords have been watching them since the incident with the Ouija board, which revealed the seed of the coming transformation hidden within Jean.
