Living on the Edge is a ``how-to'' guide for intervention--in which the family, with the aid of an addiction counselor, confronts the addicted member and convinces him or her to seek treatment. It also gives concise examples of actual interventions, guidelines for conducting an intervention, and what to do if intervention fails. Drugs, Alcohol and Your Children is primarily for parents of adolescent children. Counselor Youcha hopes to reach all parents, not just those with addicts. Her aim is to help them understand how addictions occur and to suggest how to prevent a child from becoming addicted. Both guides contain excellent references for further reading and referrals to reputable centers for treatment of drug and alcohol addiction. Both are recommended for most libraries.-- Kim Banks, Columbia Univ. Libs.
