Krakauer's book, Missoula, is focused on the most common type of rape: non-stranger sexual assault. While it reports from a Montana college town, Missoula's rape statistics are about average for the U.S.
The book has been criticized which is not surprising, however, I have read it twice and find it convincing and sobering. Alcohol seems to be an almost-constant factor. Alcohol, jocks and naive students -- female and male.
This is a hugely important topic and Missoula is an important introduction. Probably, everyone in high school, college, or with children at these stages should read it. Educators are another important audience.
