The book is great as a guide for teanagers. I bought it for my son when he was 12 and I have never regreted it. I occasionally encourage him to go over it again and use it as a reference material as he grows older and faces the challenges of teanage years.
I have read the book myself and have ordered several copies as present for young adults especially as they rich 13years when they are getting exited. I also make sure I have a copy on my self to give out anytime the oppportunity comes. I gave the last copy to a friends son and he has introduced it to everyone it his school.
