Part German-American and part Chippewa, Louise Erdrich has described the “mixed blood's” quest as a search for parentage, an attempt to understand self by interrogating genealogy. In the opening paragraphs of Tracks, a novel set on a North Dakota Chippewa reservation in the early 20th century, Erdrich reveals that the investigation of background necessarily entails an entrance into the world of ghosts. When the narrator Nanapush addresses the young woman listening to his unfolding account of her familial and tribal past as a “child of the invisible, the ones who disappeared,” he simultaneously connects an awareness of the ghostly presence of the dead with the discovery of identity and the creation of history. The narrator's conjuring of “invisible ancestors and “ghosts” (2) who inhabit tribal woods introduces haunting as Erdrich's central metaphor for the way the past shapes and is shaped by the present.
