The Time Machine (Version 7) - H. G. Wells

The story follows a Victorian scientist, who claims that he has invented a device that enables him to travel through time, and has visited the future. There, he finds the human species has “evolved” into two distinct forms. Above ground live the Eloi—gentle, fairy-like, childish creatures, whose existence appears to be free of struggle. However, another race of beings exists—the Morlocks, underground dwellers who, once subservient, now prey on the feeble, defenseless Eloi. - Summary by Cliff Stone
