H.G. Wells's view of the world - and hence his writing - was strongly influenced by the biologist's training he received during his three years as a student at the Normal School of Science, South Kensington (now Imperial College, London). Those things which a creature needs in order for it and its species to thrive get particular attention in Wells's books. Tracing biological themes through Wells's work, as Peter Kemp does here, shows the pattern of his thought and brings to light the bizarre workings of a fascinating imagination. For the book's reissue in paperback, an afterword has been added.
