Our father recommended the memoir Beautiful Boy by David Sheff, and we always read the books that our father tells us to, because we are good dog-ters.
David Sheff records the details of his son's decline into meth addiction in heart-wrenching detail. The book starts with his son's birth, through a difficult divorce with complicated split custody, dating and remarriage, new children, and finally to the point where Nic starts to lose track of himself. He becomes addicted fast and early, struggling through rehab, relapse, and tragic addiction. It was fascinating to read.
Quick vote: This book was raw, wrenching, heartfelt, and touching. We loved it, but were relieved when we had finished it.
