Here are some books that are good reading...

BEAUTIFUL BOY  by David Sheff
A father tells the story of his son Nic's addiction to crystal meth.

Tweak   by Nic Sheff
The son's story of his addiction.

Broken   by William Cope Moyers
William Cope Moyers is the son of journalist Bill Moyers. In this book the son chronicles his addiction, recoveries, and setbacks.  He mixes his story with background information that explains the nature of his addictions.  This book is my favorite.
