Monsters That Once Were Men

When Captain Johnny Harmon and his crew detour to an uncharted Earth-type world for minor repairs, they expect an uneventful layover. Instead, they discover the shattered remains of a legendary lost starliner—and the grotesquely mutated descendants of its irradiated survivors watching them from the trees. As the crew learns the horrifying history of the Empress of Saturn, their brief stop becomes a desperate race to get off the planet before they too join the fate of those who came before.

Robert Silverberg delivers a gripping tale of suspense, tension, and moral unease as the line between human and monster blurs in the alien jungle. The story grapples with the consequences of radiation, isolation, and the relentless force of evolution gone wrong. What begins as salvage turns into a fight for survival when the forest's misshapen inhabitants emerge with deadly intent.
