When fourteen-year-old Hannah Salwen saw a homeless man at the same instant she spotted a man driving a glistening Mercedes, she said, "Dad, if that man had a less nice car, that man there could have a meal." Acting on her urge to do something, Hannah's family made the extraordinary decision to sell their Atlanta mansion, buy a house half its size, and give half of the sale price to a worthy charity. Their plan eventually took them across the globe and well out of their comfort zone. In the end they learned that they had the power to change a little corner of the world. Warm, funny, and deeply moving, "The Power of Half" is the story of how one family grew closer as they discovered that half could be so much more.
