Can one person really make a difference in the world? Twesigye Jackson Kaguri defied many naysayers-and his own nagging doubts-and proved that, with a dream and incredible determination, he could change many lives.

Growing up in rural Uganda, Kaguri overcame poverty to earn a degree from the national university and worked as a human rights advocate, eventually making his way to pursue studies at Columbia University. When he returned to his village in Uganda with his wife, they were overwhelmed by the plight of his village's many AIDS orphans and vowed to open the first tuition-free school in the district for these children. Faced with many daunting obstacles, including little money, skepticism among friends in both the U.S. and Uganda, corrupt school inspectors, and a lack of supplies, he doggedly built one classroom after another until they had an accredited primary school filled with students dreaming of becoming the future doctors, teachers, lawyers, engineers, and even presidents of Uganda.

"The Price of Stones" is the stirring story behind the founding of the Nyaka AIDS Orphans School. Weaving together tales from his youth with the enormously inspiring account of the remarkable challenges and triumphs of the school, Kaguri shows how someone with a modest idea is capable of achieving monumental results. His story will captivate all readers of "Three Cups of Tea" and Tracy Kidder's "Strength in What Remains."
