"Because it's there..." That was why Earth men climbed Mt. Everest and why, in 2017, they set out for the distant star, Wolf 359. In 1988, they had learned that intelligent inhabitants from a planet orbiting Wolf 359 had been signaling Earth. That fact was reason enough to dispatch a manned probe to explore and investigate. But perhaps there was another reason for the journey. A reason too incredible for Earth people ever to imagine. A reason they might never understand even when they land on the planet they call Jennings' World.
