Game On in Ancient Greece

The Binkerton children return to the Good Times Travel Agency - but this time, with a plan to travel to the future, to the next Olympic Games. But the owner of the shop misunderstands and sends the children to the ancient Olympic Games instead - in fifth-century BCE Greece! After discovering some eye-opening facts about the ancient Games, causing a pile-up at the chariot races and having to run for their lives to escape the upset locals, the trio find themselves perilously close to disaster aboard a warship! Can the children finish reading the guidebook that will transport them back to the present before it's too late?
