There is a range of topics, some of which are considered contentious or controversial, but the authors approach them from multiple viewpoints with sensitivity, balance, and impartiality. The topics are well-researched and indexed. . . . The text is clear and accessible. The use of boxes, charts, and color photos successfully adds information while providing relief from the formal text. Beneficial for research projects, but also useful for general interest reading and to encourage critical thinking about complicated issues.
