If you ever decide to travel in time, make sure you read the Rule Book first! Jeremy should be at home eating his supper. Instead he has traveled through time with a cat named Aristotle to Mount Olympus, home of the Greek gods. Neither he nor Aristotle has any idea how to get home, let alone how to help Mr. Magnus lift Zeus's curse on his theater, where no play has been performed for years. Not knowing what else to do, Jeremy and Aristotle climb toward the summit, finding adventure all the way.
