H. G. Wells's The War of the Worlds, the first story to speculate about the consequences of aliens (from Mars) with superior technology landing on earth, is one of the most influential science fiction books ever written. The novel is both a thrilling narrative and an elaboration of Wells's socio-political thought on the subjects of imperialism, humankind's treatment of other animals, and unquestioning faith in military technology and the continuation of the human species. This edition's appendices include other related writings by Wells; selected correspondence; contemporary reviews; excerpts from works that influenced the novel and from contemporary invasion narratives; and photographs of examples of Victorian military technology.
