Cyber Hacker (Choose Your Own Adventure No. 183)
You are a computer hacker of the future, and the future is really different. You are able to perform virtual reality "dives" into the computer itself--the Cyberverse--and explore limitless worlds. Which is really great, until your friend and hacking partner Greg disappears. Did the police nab Greg for hacking crimes? Or is someone or something much worse behind his disappearance?
