Children Left Behind: The Dark Legacy of Indian Mission Boarding Schools is a personal memoir from a boarding school (residential school) survivor who attended the Holy Rosary Mission on the Pine Ridge Reservation for ten years. Giago is an award-winning journalist from the Pine Ridge Reservation who also founded Lakota Times (now the Indian Country Times). His recollections are paired with heart-felt poems about his years spent at boarding school. The first part of the book presents his perspective as a survivor. The second part takes a look at the boarding school system through essay format as he discusses abuses and remedies, and traditional spirituality. Throughout the work he has added black and white photographs from his years at this Catholic institution. The entire book is a testament to the author's strength of character and determination to talk about the abuses of residential schools and shows his courage as he challenges readers to seriously examine this aspect of Native American education.
