The Thought-feeders

Dr. Kempster Duerkes and Captain Lewis Hawes set out in an experimental stratosphere scout expecting a routine test flight—and instead are swept into a dazzling, deadly encounter with the unknown. When green clouds seem to attack their plane, drain its power, and drag them into a hidden realm above the earth, the men discover that the upper atmosphere conceals an entire civilization of living cloud-beings. Inside this eerie aerial city, streets and buildings exist in a strange mental dimension where thought replaces ordinary speech. The cloud leader, Loetta, reveals the truth: the Green Clouds are a higher evolutionary form that feeds on human consciousness itself. Duerkes clings to logic and invention, while Hawes's instinctive, imaginative mind proves especially tempting to their captors. As Loetta openly toys with the pilot, the two men realize they are not prisoners in the usual sense—they are prized mental livestock in a society that nourishes itself on ideas, emotions, and imagination. Blending science fiction wonder, sly humor, and escalating peril, the story pits human certainty against a civilization beyond comprehension.
