This best-selling book from Michael W. Smith has sold over 150, 000 copies. As relevant today as when Michasel first wrote it, Old Enough to Know gives straight, Biblical answers to the struggles of growing up: sex, drugs, alcohol, peer pressure, parental conflict, friendship, goals, responsibilities and materialism. Calling it "a book for my friends, " the author assures teens that he knows they are old enough to know the difference between the phony and the genuine, and attempts to show how he – and other adults! – have genuinely "been there" and can help.
