Grade 9 Up—This series entry gives a brief history of marriage from its beginnings as "an early and vitally important human invention" through the arguments for and against legalized same-sex unions. Stefoff also explores issues related to marriage such as the role of religion and divorce. Designed to spark discussion in the classroom and across the cafeteria table, this title provides solid facts and figures, and the author makes the point that groups on both sides of the issues can successfully use statistics to support their cases. Her balanced presentation will allow readers to draw their own conclusions as the definition of the institution continues to evolve. This well-researched volume is supported by chapter notes and a solid selection of books and Web sites for further reading.
