The articulate and intelligent ""advocate for Catholic living in suburbia"", Father Andrew M. Greeley, takes a long, appraising look at Catholic teenagers -- the present day Strangers In the House -- in this worth while, up-to-the-minute book. Young people of the sixties, about whom Father Greeley writes with such penetrating clarity, have never known a depression and can't remember a major war. They have never suffered privation of any kind, and have had more material things showered on them than has any group of young people in the history of the race. Yet they aren't as happy as they should be, and they to have lost the vigor, drive, and the enthusiasm which we expect of young Americans. The supposedly ""good life"" of their parents, the only goal held up to them as worth attaining in this Age of Apathy, does not look very rewarding, very appealing or very challenging. It looks more like the rat race which it is and hardly worth fighting for. Father Greeley delves deeply into the reasons why teenagers drink, cheat and go steady. Then he considers the ways in which everyone who has authority and responsibility for youth might best work ""to educate the young to a Christian consciousness"", for only in true Christianity can a young person find his identity in service to others. Strangers In the House is hardly a comforting book, pointing up as it does the harsh truths of the time which many parents prefer to ignore. But parents willing to be shaken from their complacency will welcome this important book which deserves to be reviewed at every high school PTA meeting this year. Certainly Strangers In the House deserves the close attention of teachers, counselors and priests as well as parents.
