Query: Great Book For Teenagers

I thought this book was really good. I bought it a year ago and I still read through it about once a month, just to keep me in line. It offers great examples to teens and gives a good perspective. John Bytheway is my favorite author and youth speaker and I was glad to have met him over the summer. I encourage parents to buy this for their teens.
