A Day with Hu'ul by Jose and Kerrie Cázares. A day in the life of Tohono O'odham girl with her grandmother. This book teaches not only O'odham words but traditions as well.
This is a good book for Tohono O'odham that want to preserve their himdag (traditional way of life). It is also a great book for non-O'odham that are interested in O'odham culture.
