The Time Machine by H.G. Wells

The first great novel to imagine time travel, H. G. Wells’s The Time Machine (1895) follows its narrator on an incredible journey that takes him eventually to the earth’s last moments. When a Victorian scientist invents a machine that allows him to travel to the year A.D. 802,701, he encounters a highly evolved society of people called Eloi, for whom suffering has apparently been replaced by refinement and harmony.

First impressions are misleading, however, and his discovery of the Eloi’s true relationship to the brutish Morlocks who lurk in tunnels beneath them leads him to a horrifying insight into the fate of mankind and its roots in his own time.
