Leave Earthmen or Die!: Three Earthmen. Three Familiar Voices. One Deadly Warning.

The warning was unmistakable: Leave, Earthmen—or die!

Murph, Forsyth, and Jamison have crossed space to reach a distant world that could become humanity’s next colony. But before they can even begin their mission, a mysterious voice delivers a simple command—go away.

That should be impossible. There are no people here. No cities. No visible civilization waiting to defend the planet. Yet something knows the Earthmen have arrived, and whatever it is seems determined to drive them away.

Then the warning becomes personal.

Each of the three men hears a different voice. To one, it sounds like someone he once loved. To another, someone painfully familiar. Each voice reaches into memories that should be private, exploiting emotions and relationships no alien intelligence should know anything about.

The men have traveled together to the same planet, but suddenly they aren’t experiencing the same world.

Is someone—or something—actually speaking to them? Are the voices hallucinations? Or has an alien intelligence discovered a far more effective weapon than guns, bombs, or armies?

The deeper the Earthmen venture, the more dangerous the mystery becomes. The planet doesn’t need to overpower its visitors when it can reach directly into their minds.

Leave, Earthmen—Or Die! by John Massie Davis is a vintage science fiction tale of alien contact, psychological warfare, and three explorers confronting an enemy they cannot see or understand.

What would you do if an alien world warned you to leave—and delivered the warning in the voice of someone you could never ignore?
