The Blind Side by Michael Lewis

In football, as in life, the value we place on people changes with the rules of the games they play.
When we first meet the young man at the center of this extraordinary and moving story, he is one of thirteen children by a mother addicted to crack; he does not know his real name, his father, his birthday, or any of the things a child might learn in school. And he has no serious experience playing organized football.
What changes? He takes up football, and school, after a rich, Evangelical, Republican family plucks him from the mean streets. Their love is the first great force that alters the world's perception of the boy, whom they adopt. The second force is the evolution of professional football itself.
In THE BLIND SIDE, Lewis shows us a largely unanalyzed but inexorable trend in football working its way down from the pros to the high school game, where it collides with the life of a single young man to produce a narrative of great and surprising power.
