Space-opera heroines, gender-bending aliens, post-apocalyptic pregnancies, changeling children, interplanetary battles of the sexes, and much more- a groundbreaking new collection of classic American science fiction by women from the 1920s to the 1960s Warning- the visionary women writers in this landmark anthology may permanently alter perceptions of American science fiction, challenging the conventional narrative that the genre was conceived mainly by and for men. Now, two hundred years after Mary Shelley's Frankenstein, SF-expert Lisa Yaszek presents the best of the female tradition in American science fiction, in the most comprehensive collection of its kind ever published. From Pulp Era pioneers to New Wave experimentalists, here are over two dozen brilliant writers ripe for discovery and rediscovery, including Leslie F. Stone ( The Conquest of Gola, 1931), Judith Merril ( That Only a Mother, 1948), Leigh Brackett ( All the Colors of the Rainbow, 1957), Kit Reed ( The New You, 1962), Joanna Russ ( The Barbarian, 1968); Ursula K. Le Guin ( Nine Lives, 1969), and James Tiptree Jr. ( Last Flight of Dr. Ain, 1969). Imagining strange worlds and unexpected futures, looking into and beyond new technologies and scientific discoveries, in utopian fantasies and tales of cosmic horror, these women created and shaped speculative fiction as surely as their male counterparts. Their provocative, mind-blowing stories combine to form a thrilling multidimensional voyage of literary-feminist exploration and recovery.
