Makina's descent north to find her brother
Makina runs the switchboard in a small Mexican mining town and speaks her native tongue, Spanish, and English. Her mother sends her across the border to bring home her brother, who went north to claim a promised plot of land. Aided by local crime bosses, she crosses a river, desert, and city, and learns that her brother has taken another man's identity and fought in the US army. The book's nine chapters track the nine levels of the Aztec underworld, Mictlán.
