Read the following excerpt from “Homecoming.” Inside the hogan, Grandmother, Mother, and Father were preparing a Blessing Way ceremony in anticipation of Nantai’s arrival. His brother was coming home, back to the sacred land of his people, the Diné. It had been three years since Nantai had been rounded up by agents of the federal government while herding the family’s sheep and taken to boarding school to learn the White man’s ways.

Although the Navajos had agreed to have their children attend school as part of a decades-old treaty with the United States government, many Navajo families, like Atsidi’s, were not willing to send their children away from their sacred homeland. As a result, children were taken and enrolled without their parent’s consent. Nantai was one of those children. He had been 15 years old the last time Atsidi had seen him.
