The only thing wrong with Jon Ronson is that he hasn't written more books! This is the third I've read (I think he has three more out in the UK), and I've loved every one. His best-known work is The Men Who Stare at Goats, which was made into a movie that I haven't seen. Ronson chooses interesting subjects, and I enjoy his writing style. In this "Journey Through the Madness Industry", Ronson learns what defines a person as a psychopath and looks for those traits in various people, including criminals, CEOs, and himself as a journalist.
I bought this book at a Borders bankruptcy sale (the Orland Park store, I think, where I once did a Biking Illinois signing event). It sat in my massive stacks of unread books until I saw Ronson on The Late Late Show with Craig Ferguson about 4-6 weeks ago. They didn't talk about the book much -- Ferguson was more interested in talking about Ronson's wife, who had been the hottest girl in Ferguson's high school -- but the appearance reminded me how much I enjoy Ronson's books.
