Nine-year-old Betita knows she is a crane. Papi has told her the story, even before her family fled to Los Angeles to seek refuge from cartel wars in Mexico. The Aztecs came from a place called Aztlan, what is now the Southwest US, called the land of the cranes. They left Aztlan to establish their great city in the center of the universe-Tenochtitlan, modern-day Mexico City. It was prophesized that their people would one day return to live among the cranes in their promised land. Papi tells Betita that they are cranes that have come home.
