Speculative fiction—encompassing both science fiction and fantasy—has emerged as a dynamic field within Chicana/o and Latina/o studies, producing new critical vocabularies and approaches to topics that include colonialism and modernity, immigration and globalization, race and gender. As the first collection engaging Chicana/o and Latina/o speculative cultural production, Altermundos: Latin@ Speculative Literature, Film, and Popular Culture provides a comprehensive alternative to the view of speculative fiction as a largely white, male, Eurocentric, and heteronormative genre. It features original essays from more than twenty-five scholars as well as interviews, manifestos, short fiction, and new works from Chicana/o and Latina/o artists.
