Alien beings attempt contact with Earth, but their animal-like emotions prevent them from understanding humans. When astronauts discover a giant frozen creature and a scroll containing an ancient language, the aliens' leader believes it may be an archaeological find from the 21st century that will provide answers to their questions about Earth. As the astronauts examine more bodies in the alien craft, the aliens plan to analyze the scroll's language to unlock its secrets.

Contains 4 stories
Blueprint for Survival
5 pp · Science Fiction

When enemy powers threaten global destruction, the brilliant young scientist Wayne Gamma presents a radical plan: a precision rocket that proves the world's aggressors are outmatched, forcing them to the negotiating table. As Gamma joins an ambitious space program, his superhuman dedication and uncanny knowledge begin to raise troubling questions about his true origins—questions that lead to a revelation far stranger than anyone anticipated.

Moon Freighter
3 pp · Science Fiction

A supply run to the Moon's United Nations mining site takes a catastrophic turn when a meteorite tears into the freighter's hull—until Jensen, Holbrook, and Spears receive an unexpected telepathic message from an unseen intelligence ordering them to stay put. What unfolds is an encounter with benevolent visitors from another world who offer an extraordinary solution to the crew's crisis.

The Trespassers
6 pp · Science Fiction

Mystery descends on Earth when egg-shaped objects simultaneously land in major cities worldwide, surrounded by an impenetrable invisible barrier that defies all investigation. As soldiers, scientists, and world leaders struggle to breach the shield and uncover the visitors' purpose, a shocking truth emerges from within—one that challenges everything humanity believes about the strange trespassers in their midst. This 1959 tale captures the Cold War anxiety and wonder of the atomic age, asking whether some encounters are meant to remain mysteries.

The Mighty Tomb
10 pp · Science Fiction

Dr. Fennelly and Paul Gray pilot the atomic-powered drill-ship "the Mole" on humanity's first expedition into Earth's depths, passing through layers of rock and underground lakes as they descend miles below the surface. When the drill becomes impossibly stuck against an impenetrable barrier over 400 miles down, they discover something extraordinary: vast machinery and the perfectly preserved body of a giant, along with a mysterious scroll that holds the key to an astounding truth about their world.
