Revealing the intriguing mindsets and winning strategies of some of the world's most unconventional entrepreneurs, The Power of Unreasonable People: How Social Entrepreneurs Create Markets That Change the World, a new book by John Elkington and Pamela Hartigan (published by Harvard Business Press, February 5, 2008), shows how these social entrepreneurs are solving some of the world's most pressing economic, social, and environmental problems -- and in the process are creating growing markets across the globe.

The book describes how unreasonable entrepreneurs build their enterprises – and some of the challenges they face on the way. It lays out implications for future markets. And it powerfully calls for leaders in business and beyond to help social entrepreneurs reach their full potential.
