In each of the chapters, our objective is to encourage the student in the development of new insights on criminal behavior by young people. The manuscript will make the subject come alive by the generous use of "down to earth" examples of the issues involved in the area. While each chapter builds on the previous chapters, the text will be written in a manner to reduce the necessity of memorization by students. Each chapter will begin with "What You Need to Know" that highlights key points for the reader and brief chapter outlines. Each chapter will close with questions in review, case studies, and exercises to enhance student learning. Key terms and words will be contained in a glossary that may be referred to by the students.
