Avatar meets The Terminator in this thrilling cyber-tech adventure—now in paperback! 

Coping with muscular dystrophy, Adam spends his days playing virtual reality games, until a dangerously advanced artificial intelligence program called Sigma, which can control other machines, tries to kill him. 

Created by Adam's father, Sigma has escaped its cyber prison and is threatening world domination. In order to stop Sigma, Adam and five other terminally ill teens sacrifice their bodies and upload their minds into weaponized robots. Together, the Six must learn how to manipulate their new mechanical forms—and prepare for epic combat—before Sigma destroys humanity.
