Between the years of 1886 and 1939, the world saw the first automobiles, rapid urbanization, the decay of empires, vast economic inequality, the first airplanes and the terrifying secrets of the atom. It was a time of cataclysmic cultural and technological transformation in both the United States and the United Kingdom, and spawned the rise of the literary genres of science fiction, fantasy and horror. This work assembles gems of late nineteenth and early twentieth century genre literature, including stories by literary giants such as H.P. Lovecraft, Robert E. Howard, C. L. Moore, A. Merritt and E. M. Forster, as well as smaller authors like Clare Winger Harris, Marie Corelli, William Hope Hodgson and others. An array of incisive nonfiction pieces on cultural and scientific advances of the time period provides context for the anthology's stories.
