Very interesting in a Criminal Minds sort of way. The premise of this book is that you should listen to your intuition, because it is unconsciously cataloging all sorts of things that your logical mind will only realize after the fact. Lots of examples of people who just "knew something was wrong" somehow and got out of the situation, or people who DIDN'T and had something terrible happen to them.

I'm not too terribly sure how useful all this will be when you're walking home and get randomly attacked by a serial killer. After all, de Becker claims that your intuition would warn you anyway whether you read the book or not; if your intuition doesn't warn you, or if it's warning you all the time about things that do turn out to be innocuous, there's not much more hidden in this book that will help you out in that situation.

The Gift of Fear does have a lot to say, though, if you've ever dated/been in a relationship with/tried to get out of a relationship with a dangerous or abusive person. It covers a lot of wise, useful concepts from danger signs of future abuse in people you might date, to how to deal with stalkers, and the best way to leave abusive situations.
