Business leaders/social visionaries Jeremy Heimans and Henry Timms provide the tools for using new power to successfully spread an idea or lead a movement in the twenty-first century. Drawing on examples from business, politics, and social justice, they explain the new world we live in - a world where connectivity has made change shocking and swift and a world in which everyone expects to participate.
