This book can be ordered on http://www.triplep-america.com as it is not in your local Barnes & Noble but can be ordered through the Triple P (Postive Parenting Program) network in South Carolina.
I thought this was a useful book for parents, written by an Australian so missing some of the americanisms which annoy me (although they usually don't detract from the advice). Easy to follow advice and a good explanation of positive parenting.
