Author Lindsay Levin, who founded the social enterprise Leaders' Quest in 2001, tells the stories of some of the people she has met through her work, and their impact on the world. Levin takes readers on a journey from Canary Wharf to the streets of Mumbai, and from a high-security prison in Johannesburg to Chengdu, where thousands of new tower blocks are transforming the city. We meet individuals who are overcoming obstacles, and often their own frailties, to change the lives of those around them. The invisible giants of Levin's story are grassroots leaders who, despite a lack of education and resources, are re-energising their communities, and business executives who strive to integrate purpose alongside profit, in the face of institutional resistance. They are female activists in slums campaigning to end the exclusion of girls from school, and environmentalists tackling the effects of industrialisation on the world's ecosystem. They are also ordinary Israelis and Palestinians committed to peaceful coexistence who are delivering a courageous and sometimes unpopular message to their own people. "In my experience, people have infinite potential to grow and to create. I have written this book to try and share some of this optimism," says Levin. After 15 years as a successful entrepreneur, Levin founded the social enterprise Leaders' Quest in 2001, to bring together people from all disciplines and sectors who want to use their unique influence to create positive change in the world. Her work has brought her into contact with an extraordinary range of leaders from across the world - some highly visible, and some not.
