Unexpected Stories is, by any measure, an unexpected gift. This slender but resonant volume contains two stories—recently unearthed and never before in print—by one of the most significant figures in modern science fiction: Octavia E. Butler.

“A Necessary Being” takes us into the heart of an alien culture with a rigid hierarchical system based on caste and skin coloration. With the arrival of visitors from a distant mountain tribe, the society known as the Rohkohn finds itself faced with the sudden prospect of profound social change.

In the second story, “Childfinder,” the title character is a woman who uses her psychic abilities to track down children with similar nascent abilities—and protect them from the abuses of a predatory society.

The Subterranean Press edition features a newly-commissioned introduction by Nisi Shawl, and an afterword by Butler’s longtime agent and literary executor, Merrilee Heifetz.
