The introduction of Children Left Behind begins with the desperate cries of a past student tormented by the memories of a life that is not left far behind. This isn't the first book that Tim Giago has written, this is more like the second edition and clean cut version of the original, The Aboriginal Sin. Some journalists who reviewed the book called the staff of the Holy Rosary, now known as Red Cloud Indian School, to confirm that Giago was once a student and that his poems were legit. Priests who tended to the calls informed the curious journalists that Mr. Giago was never a student at "Red Cloud," which wasn't a lie but theoretically he attended Holy Rosary. It was a throw off to defend the previous behaviors of the prefect that once caused the hurt of so many children. This book is the outcome of furious members of the Catholic Religion who felt that Giago was "bashing" the religion as a whole and that his poetry was a definitive passage of writing to degrade priests and nuns alike. As stated by Tim Giago, he is "speaking for the once-silenced voice." The first chapter reminisces about the negative experiences that Mr. Giago and his peers went through. There was sexual abuse, beatings, and verbal abuse to name a few. He states, "this book is intended to bring back the memories of the boarding schools to those who have survived them. It is also intended to cause those memories, good and bad, to bring about a process of healing that has long been denied. But more than that, it is written to bring out the truth that has been hidden for too many years."

Like Chilacco, Mr. Giago brings out the good and bad feelings that he, as well as many other student have experienced while attending an indian boarding school. The beginning is also similar in that it gives a general history of the school and how it was started.

Unlike Chilacco, Children Left Behind has a much darker undertone behind the writing. The author talks much of the negative aspects of being a child stolen from the life he once knew. Every child has a different experience and this was his story through vicarious poetry that pierces even the happiest of times.
