To read more from H.G. Wells, students should read The Time Machine (1895), The Invisible Man (1897), or The War of the Worlds (1897). These books will offer a further connection between the social climate Wells was living in and his desire to write science fiction with societal allegory.
For other texts that take place on islands or post-shipwreck, students should read Robinson Crusoe (1719) by Daniel Defore or The Mysterious Island (1874) by Jules Verne.
Books containing other strong themes of social allegory include Animal Farm (1945) by George Orwell or Lord of the Flies (1954) by William Golding.
