Light in the Dark also contains important developments in Anzaldúa’s theories of nepantla and nepantleras, spiritual activism, new tribalism, nos/otras, conocimiento, autohistoria, and autohistoria-teoría, as well as additional insights into her writing practice and her experiences with diabetes. It invites readers to draw new insights and provocative connections between Anzaldúa’s landmark text, Borderlands/La Frontera, and her later writings. Anzaldúa viewed Light in the Dark as both a dissertation and a publishable book; she prioritized it during the last years of her life but passed away before it was published. For a more comprehensive discussion of its history, see Keating’s introduction to the volume.
