This splendid book is more than a primer on social entrepreneurship for human rights in the developing world. It is also a compendium of searing testimony about the immense practical challenges that idealistic changemakers can overcome by dint of their unflagging energy, incandescent visions of humanity and justice, and on-the-ground skills and resourcefulness. Zachary Kaufman has performed a great public service in orchestrating this admirable volume about how hope for the future can be vindicated even under the most unpromising conditions.”
