An immediate bestseller when first published Pay It Forward captured hearts all over the world became a wildly popular film and spawned a generation of increased altruism. This anniversary edition includes a new introduction by the author. It takes an inspiring and moving tale of a young boy who believed in the power of kindness and brings it to a new generation of readers. Twelve-year-old Trevor McKinney accepts his social studies teacher's challenge: come up with a plan to change the world. His idea is simple: Do a good deed for three people and ask them to pay it forward to three others in need. He envisions a vast movement of kindness and goodwill spreading beyond his small California town and across the world.
