The First Olympics

From the Back of the Book: You are a contestant in the first Olympics! You and your cousin Felix are touring Olympic ruins in Greece when you wander into a dark cave. Suddenly you find yourself caught up in a procession of athletes that passes ivory-white temples along the road. You've travelled back in time to the ancient Olympic games! The contests are about to begin, and now you're a competitor. Will you sign up to compete in the wrestling event, or test your skills as a chariot driver?
