Flame Tree 451 presents a new series, The Foundations of Feminist Fiction. The early 1900s saw a quiet revolution in literature dominated by male adventure heroes. Both men and women moved beyond the norms of the male gaze to write from a different gender perspective, sometimes with female protagonists, but also expressing the universal freedom to write on any subject whatsoever. Each book features a brand new biography and a new glossary of Literary, Gothic and Victorian terms.
