Gavin Duncan is a planter on the distant planet Layard, struggling to protect a vital medicinal crop from a strange native creature known as the Cytha. When the animal begins raiding his fields, Duncan launches a relentless hunt across blistering plains, treacherous ravines, and alien forests, convinced that no creature is beyond human skill or firepower.
But Layard does not operate by human rules. As the pursuit intensifies, Duncan uncovers a world shaped by unfamiliar biology, unsettling loyalties, and a form of life that adapts with disturbing intelligence. What begins as a practical hunt becomes a confrontation with an entire planetary system that challenges human assumptions about dominance, survival, and responsibility.
Clifford D. Simak was one of science fiction’s great humanists, known for blending speculative ideas with deep moral and philosophical insight. Rather than focusing on technology alone, Simak explored how humanity fits into larger cosmic ecosystems, often portraying aliens not as enemies, but as mirrors reflecting human flaws.
Best known for works such as City and Way Station, Simak’s stories are thoughtful, quietly powerful, and enduringly relevant. The World That Couldn’t Be exemplifies his ability to turn an adventure premise into a profound meditation on coexistence and restraint.
