Loose Change (Doubleday: Garden City) is a non-fiction biography from 1977 by the American author Sara Davidson. The book follows the changing fortunes, lives, friendships, attitudes and characters of three women, beginning with their meeting as freshmen at the University of California, Berkeley in the 1960s. Sara (Davidson), Susie, and Tasha experience the radical changes that went through American culture in that era, observing or being involved in student protests, drug use, the Civil Rights Movement, the 1968 Chicago Democratic Convention, communes, free sex, and the popular music of the times. Over the course of the book, they become closer and then diverge in their viewpoints and propinquity.
