Query: Harrowing tale of descent from the heights

Having personally known friends who were heroin addicts, this is a story that speaks to my heart, and should be a "must-read" for all who dabble in designer drugs and such.Negron was at the top of the world with one #1 song after another, but in the end, the gutter was his home. This is a story that (at the moment) has a happy ending, and credit should be given to the woman who stuck by him, and to Chuck himself for turning his life around.This story transcends music, although fans of Three Dog Night will find interesting tidbits. In truth, it's a book that's hard to put down, and has all the ingredients of a gripping novel, and yet it's all true.Read this book!! Especially if you know someone who is "in trouble" or just read this book to see the full range of human depravity AND human resiliance and perserverance.
