My Decade at Old Sun, My Lifetime of Hell is a simple and outspoken account of the sexual and psychological abuse that Arthur Bear Chief suffered during his time at Old Sun Residential school in Gleichen on the Siksika Nation. In a series of chronological vignettes, Bear Chief depicts the punishment, cruelty, abuse, and injustice that he endured at Old Sun and then later relived in the traumatic process of retelling his story at an examination for discovery in connection with a lawsuit brought against the federal government. He returned to Gleichen late in life—to the home left to him by his mother—and it was there that he began to reconnect with Blackfoot language and culture and to write his story. Although the terrific adversity Bear Chief faced in his childhood made an indelible mark on his life, his unyielding spirit is evident throughout his story.
