London, G. MacDonald & Co., 1926. First edition, first impression. Hardback. A very good copy. In the jacket. Inscribed by the author to the front pastedown. A rare piece of science fiction: a future war with elements of myticism. The jacket is a little chipped and toned, with a few short tears. Boards a touch marked and stained, top edge dusty. Overall, a great book. [10500, Hyraxia Books].
