Born and raised in Baltimore, Maryland, Michael Phelps began swimming at age seven at the urging of his mom. As a young boy, Michael was brimming with energy--more energy than most other kids his age--and Mrs. Phelps thought this sport could help keep him calm and focused. As Michael grew older, his skills improved, and he transformed into one of the greatest swimmers in the world, winning twenty-eight Olympic medals. Outside of the pool, Michael became an advocate for mental and physical health for adults and children. He even founded an organization that teaches water safety and promotes healthy living. Young readers can learn more about Michael Phelps's thriving legacy in this illustrated middle-grade biography.
