Science fiction has historically been seen as a masculine domain, but from the very beginning women have made their mark. To the ranks of Mary Shelley and C. L. Moore, we should add Clare Winger Harris, whose pulp stories in the early twentieth century influenced the boom of modern writers such as Ursula K. Le Guin and Margaret Atwood. In this new collection, author and scholar Brad Ricca assembles ten of Harris's greatest short stories, including The Fifth Dimension, The Fate of the Poseidonia, The Menace of Mars, and The Vibrometer.
