The two parallel worlds of Proton (science) and Phaze (magic) were out of balance and heading for disaster. In Proton, Stile was almost murdered but saved by the robot Sheen who was in love with him. In Phaze, Stile was still learning to master the magic of his alter-ego the Blue Adept and trying to find his enemy among the other Adepts. Even the infallible Oracle appeared to be involved in the conspiracy against Stile. He had to act, and act quickly, to save all that he loved, but he had no idea what he was supposed to do!
