Seems okay. There is a website makingakilling.co.uk which has FAQs and lots of photos. Don't know if the events are real or not but they are not over the top so probably no reason to think it's fictional, and the photos say that the guy has definitely been there. There was a small amount of politics I really liked because even though I did not agree with them it is stuff you definitely don't hear in the news! It was a really good read actually, because before I didn't know anything about security contractors.
