The Boy with the Invincible Fist

Born with extraordinary strength, 12-year-old Joe Fong is rejected by his father, Wei Fong, and expelled by his martial arts master. With nowhere else to go, Siobhan O'Brien takes him in, giving him a place to stay in exchange for working as a sparring partner at her boxing gym. When the ruthless Baine Family threatens to destroy the gym, Joe breaks the vow he swore never to fight again.
