"The reluctant time-travelers Josh, Emma and Libby return to the Good Times Travel Agency - this time with the future in mind. A trip forward in time to the next Olympic Games sounds like fun, doesn't it? But instead of traveling to the next Olympic Games, the siblings wind up at the ancient Olympic Games - in 5th century BCE Greece! Emma wants to go home and quick, Josh wants to stick around and watch the athletes compete and Libby wants to join the competition. After a close encounter with some hoplites, a chaotic chariot ride and a dangerous trip on a trireme, the trio are all ready to go home - but they'll have to finish the Guidebook before disaster strikes again. Is speed-reading an Olympic event? Kids won't want to miss this rollicking, all-inclusive trip back in time!"-- Provided by publisher.
