Adam's muscular dystrophy has stolen his motility, his friends, and in a few short years, it will take his life. Virtual reality games are Adam's only escape from his wheelchair. In his alternate world, he can defeat anyone. Running, jumping, scoring touchdowns: Adam is always the hero. Then an artificial intelligence program, Sigma, hacks into Adam's game. Created by Adam's computer-genius father, Sigma has gone rogue, threatening Adam's life-and world domination. Their one chance to stop Sigma is using technology Adam's dad developed to digitally preserve the mind of his dying son.
