"Trevor McKinney, a twelve-year-old boy in a small California town, accepts his teacher's challenge to earn extra credit by coming up with a plan to change the world. His idea is simple: do a good deed for three people and instead of asking them to return the favor, ask them to 'pay it forward' to three others who need help." -- Provided by publisher.
