After sixteen-year-old Scott Freeman figures out secret code words and wins the first Star Park world-sized virtual reality adventure on the new Star Park space station two months ago, over a million persons have demanded to be added to a waiting list to be in line for the next world-sized virtual reality adventure. Everyone around the globe keeps going wild for more information. But then the mysterious General Z shows up unexpectedly with a top secret military project. All Scott's plans are scrambled now. With little explanation, Scott is rushed back to Star Park to once again enter a world-sized virtual reality adventure. But then the picture becomes horrifyingly clear. This time Scott must use the virtual reality adventure, not for amusement, but to figure out secret code words, and also from inside the adventure, to simulate a solution to save Earth from an impending, completely unexpected, threatening, cataclysmic disaster.
