Herland

Gilamn's feminist novel, Herland was one of a flood of utopian books at the turn of the 20th century where sex roles are inverted. Gilman imagined a society where women not only rule, but are the only gender. Reproducing by parthenogenesis, they worship a female deity. This particular book later became a must-read for the second-wave feminists, particularly the 'separatist' wing.
