London, Octagon Press, 1974. First Edition. First Impression. Hardback. A very good copy. Signed by the author with the date 15th May 1978 and no further inscription. An important contribution to feminist science fiction [Shinn, in her 1988 'Worlds Within Women', covers Lessing's contribution to feminist SF in great detail]. Adapted for the big screen in 1981 starring Julie Christie. Spine a little faded to the jacket. Price-clipped. Spine tips bumped. Otherwise a neat copy. [7865, Hyraxia Books].
