When the women of the Wellesley class of 1969 entered the ivory tower, they were initiated into a rarefied world. Many were daughters of privilege, many were going for their "MRS." But by the time they graduated four years later, they faced a world turned upside down by the Pill, NOW, student protests, the counterculture, and the Vietnam War.

In this social history, Miriam Horn retraces the lives of women caught on a historic cusp. This generation was the first to test-drive modern rules that remain complicated and contentious regarding sexuality, marriage, motherhood, paid work, spirituality, aging, and the difficulties of reconciling public and private life. The result is a story of uncommon subtleties and vibrancy that reflects this generation's fateful choices.
