A collection of the year's best science fiction and fantasy short fiction selected by New York Times bestselling author of the Silo series Hugh Howey and series editor John Joseph Adams. "These are dangerous stories. The kind that warp reality and threaten to change the world" warns guest editor Hugh Howey in his introduction. The Best American Science Fiction and Fantasy 2024 promises a treasure trove of audacious characters, daring worldbuilding, and twisted realties. A sibling duo of supernatural hitmen. A traveling spellbreaker and his trusty alligator mount. Superheroes registering for work. Sentient spaceships with an AI-human interface grow up together with their human pilots. From a Korean folk-tale retelling about the goddess of shamans, to a car, resurrected from obsolescence via automancy, for a road trip from California to Maine, these are stories that, for Howey, "challenged my worldview, that made me exercise new mental muscles, and that brought me to tears." The Best American Science Fiction and Fantasy 2024 includes A.R. CAPETTA * P. DJÈLÍ CLARK * JAMES S.A. COREY * AMAL EL-MOHTAR * ANDREW SEAN GREER * GRADY HENDRIX * ANN LECKIE * SAM J. MILLER REBECCA ROANHORSE * and others
