Historically, science fiction has a reputation of being created by men for other men. Women who wrote speculative fiction often used their initials or male pseudonyms to conceal their gender. During the '50s and ‘60s, only 10 percent of pulp fiction stories were written by women, many of whom have since been lost or forgotten.

This anthology attempts to preserve the place of women in American society and imagination by collecting some of the best stories by women pulp writers, including Katherine MacLean, Greye La Spina, Judith Merril, Sonya Dorman, Alice Eleanor Jones, Sophie Wenzel Ellis, and Francis Stevens.
