"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. They learned in 1988 that intelligent inhabitants from a planet orbiting Wolf 359 had been signalling Earth. That fact was reason enough to dispatch a manned and womaned 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.
