If you want details about what happened at Virginia Tech go someplace else. The book is about 1/4 of her experience with Cho and her failure to get the people above her concerned about the possible danger. Another 1/4 concerns her own experiences growing up in Sierra Leone, educated and teaching in England and then coming to America and teaching 25 years at Tech. It is about 1/4 a description of the internal bureaucratic politics of Tech as an institution. For example I did not know until after reading the book that the current President of Tech, five of his inner cabinet and Frank Beamer, the football coach are all members of 67 Tech graduating class as undergraduates. Finally another 1/4 is a summary of the current pop psychology and pop sociology literature on the recent school shootings from Columbine to Tech.
