Adventures in Odyssey: The Great Escape

From the publisher:

Eugene has just invented a life-size virtual reality game and invites Michael and Mandy to be the first to try it out. But when Michael removes the Safety Protocols, the virtual reality game turns into a very real struggle, pitting Michael and Mandy against the Computer's brain - a hyper-intelligent enemy known as Seepi Yu. Can Michael and Mandy outwit Seepi Yu and make it back to safety? Or is this "GAME OVER?" To make their Great Escape they must complete 7 games, collect valuable email messages, and along the way learn lessons about moral character and the importance of time, good choices, and responsibility.
