"The Gift of Fear" the book by Galvin DeBecker is one of the best self defense books I have ever read!!! Amazing!! It is required reading for our college students who take our self defense class. There is so much great information in this book and you can get it for about $7.00. I think everyone should read this!
It was on the New York Times Best Sellers List for like a year. I think anyone (esp. those who teach self defense) would benefit from the read.
