"This is not the book I thought I was going to write," Coontz admits. She intended to show that marriage was not in crisis; merely changing in expected ways. But her exhaustive research suggested the opposite was true. Tracing matrimony’s path from ancient times (when some cultures lacked a word for "love" and the majority of pairings were attempts to seize land or family names) through present day, she closely examines the many external forces at play in shaping modern marriage. Coontz details how society’s attempts to toughen this institution, have actually made it more fragile. Her rich talent for analyzing events, statistics, and theories from a myriad of sources—and enabling the reader to put them all in perspective—make this provocative history book an essential resource.--Liane Thomas
