Tom Swift and the Visitor from Planet X

Tom Swift and his associates at Swift Enterprises wait breathlessly for what may well be the most important scientific event in history—the arrival of the visitor from Planet X—a visitor in the form of energy. Even as the intrepid young inventor works to perfect a robot body with which the energy-brain may perceive and touch the world of man, unexplainable, devastating earthquakes threaten the world’s centers of science and technology, including Swift Enterprises. Tom suspects that a ruthless rebel faction which has overthrown the government of Brungaria is behind the tremors, using the scientific secrets of the X-ians, the space beings who have dispatched the brain energy to our world. The arrival of the visitor, whom Tom has named Exman, only sets in motion the final crisis. Tom must apply all his scientific wits to uncover the meaning of the giant symbols appearing across the surface of the earth—an eerie coded warning of catastrophes to come!
