We only spent a few minutes with Nahua communities. To spend more time with them, take a look at Alan’s book “Corn is Our Blood: Culture and Ethnic Identity in a Contemporary Aztec Indian Village.” He and Pamela also have a new book coming out in 2022 called “Pilgrimage to Broken Mountain.” It’s a look at Nahua Sacred Journeys in Mexico.

Plus, if the rain gods intrigued you, take a look at Jim’s book, “The Rain Gods’ Rebellion.”
