A worthwhile book, although not entirely new subject matter in my opinion. The author uses examples from his line of work to hammer home the fact that bad people are out there, and they will do bad things, but it's not a requirement that you become a victim of their evil.
In my opinion, this is something that just about everyone should read. While some of the things in the book were (to me) obvious, such as "listen to your gut, it's usually right when it comes to survival" the reiteration was valuable. I just wish that I could convince my 20-year old daughter to read it.
