Derek Caldwell, first time author, confessor and reformist; takes his life experience battling criminal addiction into a program designed to combat chemical dependency. This will not read like any other autobiography that you have ever read before.

A Man of Substance-Cracking the Recovery Code is just one of Derek’s great ideas in the making. It is also the mentality that helped me change my troubled life which gave birth to this writing. This book is intended to be a tool, a road map and a guide book to assist those who will make a conscious decision to change.
