Aliah and Cali are 17 and 15 and live in the American state of Arizona, but they also live in the Navajo Nation, the largest of dozens of reservations that have their own governments within the United States. The sisters share their stories of what life as a teenager is like in this two-part existence. Hear about their favorite food, what they do with their friends, and what they think of the future in a tribal nation facing uncertain times. You'll also explore the history, politics, and economy of the Navajo Nation. Understanding different cultures is vital to our own and the world's future. Each book in this series provides a unique point of view from a teenager, all about the country they call home. Learn about what they like, what they think, how they live, and what you have in common. You'll have a better understanding of the CUSTOMS AND CULTURES OF THE WORLD after you read about a teenager living in another country.
