This is the story of a new kind of social revolution which has transformed the lives of millions. It has drawn oppressed Indian women out of misery and passivity, persuaded teenagers to demand safe sex and to rebel against smoking, and prompted minority students to excel in university subjects where even well-prepared students were failing. It has helped cure tuberculosis, given soldiers the confidence to face enemy fire, and organized the nonviolent overthrow of a brutal dictator. Pulitzer Prize-winning author Tina Rosenberg explains how creative social entrepreneurs are helping people to accomplish goals from losing weight to fighting terrorism, exploiting the power of positive peer pressure. Radical, optimistic and cogently argued, Join the Club will make you appreciate the power of one of humanity's most abundant resources: our connections with each other.
