Mark is the central character in this story designed to help adolescents formulate a philosophy of values. The story is well suited for use in high school social studies courses and/or in philosophy or guidance units. Mark's thoughts and actions are reported as he interacts with his family, friends, acquaintances, and individuals of authority within his school and community. The story line centers on Mark's experiences during high school. Because many of the experiences will be familiar to a wide audience of adolescents, it is hoped that they will be able to relate to them and draw meaningful value lessons from them. The story line centers on Mark's experiences trying to explain missing books to the school librarian, denying vandalism to the police, sharing hopes and problems with his peers, and contributing input to a family decision regarding a move to another city. Issues brought out in these and other adventures include rights of citizens in a democratic society; rights and responsibilities of an individual to family, school, and community; decision-making processes in personal and social contexts; inequality in society; conflicts between people in different strata of society; and gaps between youthful idealism and adult conservatism.
