American Catholic teen-agers and their parents should welcome this book of practical information and advice touching the major problems of adolescence. In the light of Catholic principles, the author speaks directly to the teen-ager about matters affecting his religious, moral, social, psychological and physical development. There is a chapter dealing with sexual matters that has been relegated to a physician to write. The general style of the book is one that should be found acceptable by the teen-ager, and the information and advice are such as all normal Catholic adolescents are in need of, some of them very badly. How the teen-ager with abnormal difficulties -- and today so many of them fall into this category--will react to or benefit, from such a volume as this it is difficult to say. Recommended generally to Catholic priests, teachers, parents and adolescents for immediate reading and long-range reference.
