What an interesting book. Quick read. I was a bit disappointed at times; for the majority of the stories, he seems to have written down, verbatim, what his mini interview with his subject brought to light.
What I likely enjoyed most was his introduction to each story. He'd tell a bit about each approaching person, and it almost seemed like a journal.
In summary -- interesting book, but I don't know if I'd use a credit on it unless I had an abundance of them.
