Like millions of others around the world, Karl Huber is crazy about Olympus - the new full-cyber-suit, multi-player, virtual reality game on the Internet - even though his father hates it. When Mr. Huber forbids his son to play the game in his house any more, Karl's jealous brother, Jacob, seizes the opportunity to tempt his twin to run away. With trails leading in all directions, now he could be anywhere on earth. The only way to find Karl is to look for him in Olympus, where sinister forces are using high technology to build a world too fascinating for children to resist, and too profitable and powerful for adults to ignore. -From back cover
