This book was a Bob recommendation (from The Culture Show, I think?), and I loved it. Tony Parker went to a London housing estate and interviewed many of people who lived there. The book itself is made up almost entirely of the people's own words, with just a few paragraphs here and there which are Parker's description of the people/surroundings. Young people, old people, men, women, people who hate living there, people who love it, etc. The stories aren't always happy ones, but they're little slices of life. It really sucks you in, and, in a way, it's almost voyeuristic--it's like you get to peer in through the windows of many of the homes on the estate. Also, the interviews were conducted over time, and in many cases you can see how the interviewees became more frank with Parker as they got to know him and felt more comfortable talking to him.
All in all, I highly recommend it. In fact, I loved it so much that I'm now reading another book of Parker's: The Violence of Our Lives: Interviews With American Murderers. This one will likely be far more morbid, but hopefully just as fascinating.
