I started this book a while ago but had to put it down while reading for school. The irony is that this book has significantly informed my studies of crime and violence. The work of criminologist Lonnie Athens is groundbreaking and convincing (you'll have to read the book to learn what his decades of studies reveal about violent offenders!). I'm certain the communication of this knowledge was greatly facilitated by the fantastically clear and engaging writing of Pulitzer Prize-winning Richard Rhodes. I think the best thing for an academic is to have a Richard Rhodes caliber writer tell the story of their work! Highly, highly recommended.
