When three people in Philadelphia inhale dust developed by a scientist who has discovered parallel universes, they are transported into an interdimensional no-man's-land that is populated by supernatural beings. From there, they go on to an alternate-future version of Philadelphia--a frightening dystopian nation-state in which citizens are numbered, not named. How will they escape? In The Heads of Cerberus and Other Stories, introduced by Lisa Yaszek, you will find this world-bending story as well as five others written by Francis Stevens, the pseudonym of Gertrude Barrows Bennett, a pioneering science fiction and fantasy adventure writer from Minneapolis who made her literary debut at the precocious age of 17.

Often celebrated as "the woman who invented dark fantasy," Bennett possessed incredible range; her groundbreaking stories--produced largely between 1904 and 1919--suggest that she is better understood as the mother of modern genre fiction writ large. Bennett's work has anticipated everything from the work of Philip K. Dick to Superman comics to The Hunger Games, making it as relevant now as it ever was.

Francis Stevens (Gertrude Barrows Bennett, 1884-1948) was the first American woman to publish widely in fantasy and science fiction. Her five short stories and seven longer works of fiction, all of which appeared in pulp magazines such as Argosy, All-Story Weekly, and Weird Tales, would influence everyone from H.P Lovecraft to C.L. Moore.
