I've read one of the The Peaceful Warrior books and still have it around somewhere. 12 years clean & sober myself...
A handful of *really* good spirituality/recovery/inspirational books I've read and can recommend are:
"Illusions: The Adventures of a Reluctant Messiah" by Richard Bach - Excellent short story that will have you looking at life and spirituality in a new light.
"Island" by Aldous Huxley - Utopian novel with amazing insights into the difference between real spirituality and dysfunctional religiousity. Loosley based in Buddhist and Eastern philosophy.
"Healing the Child Within" by Charles L. Whitfield - a little technical for some perhaps but excellent for building self and other awareness and self-esteem.
"Your Many Faces" by Virginia Satir - cute and funny but with great depth. Covers complex subjects in laymans terms and is fun to read and easy to understand.
"Families and How to Survive Them" by Robin Skynner & John Cleese (yes, the guy from Monty Python) - I can't say enough good things about this book... mind-blowing insights into life, human nature and "the big picture" and John Cleese will make you darn-near pee yourself laughing. Unfortunately, I lost my copy.
"The Road Less Traveled" by Scott Peck - Overall excellent book about spirituality, love, values, emotional health and more. How to believe in a personal God without having to throw out Science.
And any good book on
Cognitive Therapy. I read a really good one a few years back, but can't remember the exact title.
I've read many other good books on this and related subjects but these are among my personal favorites. If you only check out one or two of these books I highly recommend "Illusions" and "Families and How to Survive Them".
Glad to hear another young person is saying, "no" to the social indoctrination of the "I must consume alcohol and drugs to have a good time, because everyone else does" mentality
Oops! It was late when I did this and I was still in the process of recovering from caffiene withdrawal, brought on by a broken coffee machine

Forgot to mention "The Road Less Traveled" and Cognitive Therapy.
