During my first year at university, I studied Sociology amd Anthropology as an outside module. We had to discuss a book within the field out of a list, and I chose Alice Goffman's On the Run: Fugitive Life in an American City. I read the whole thing in three days because I enjoyed it that much (and obviously, knowing more about the book would help in my exam).

A lot of the facts have since slipped out of my brain, but I very much remember being enthralled at the time, so I'd highly recommend it.
