London, Methuen, 1930. First Edition. First Impression. Hardback. A near fine copy. A superlative example of science fiction and one of the earliest works to address the future on an enormous scale (in the billions of years). An important novel from an author certainly amongst the most important science fiction writers: "A literary writer for the age of Einstein" [Crossley, p3]. Some wear to the boards, but nothing to write home about. [7876, Hyraxia Books].
