The Invisible Enemy

by Jerry Sohl

About this book

A survey ship reaches a planet that seems ready to reveal its secrets through instruments, calculations and a landing party. Harley Allison, the man responsible for its computer, becomes increasingly uneasy as the evidence fails to fit the commander’s confidence.

The danger lies in understanding the surface itself, and a warning is useful only if someone is willing to act on it. Jerry Sohl’s complete September 1955 story follows the expedition through its discoveries and final outcome, retaining the original illustrations by Harold W. McCauley and Lloyd Rognan.
