Berube is a professor of English at the University of Illinois and is the author of the new book, "Life As We Know It: A Father, a Family, and an Exceptional Child." It's about the birth of his son in 1991, Jamie, who has Down syndrome, and how that has affected his family's life. Berube writes in the introduction, "individual humans like James are compelling us daily to determine what kind of 'individuality' we will value, on what terms, and why."
