This is so much more than just a game.
OLYMPUS. To Karl Huber, it’s an obsession. To his father, it’s a waste of time and money. But to his twin brother Jacob, it’s an opportunity, and when the time is right, Jacob will use it to get ahead.
When Karl runs away from home, his family and his strange new friends have no idea where on Earth he could be—but they know where he is going: the peak of Mount Olympus.
Now, they must plunge into Karl’s fantasy world to try to get him back. But they have no idea how real this “game” can get… or how dangerous!
