The Trojan War is just a game for the gods and goddesses of ancient Greece, but it's no laughing matter for Jemima and Joe Lancelot when they are transported back in time to Troy, slap-bang in the middle of the deadly conflict.
Still on the trail of their missing parents who are lost somewhere in the past, the twins, together with best friend Charlie and their talking cat Max, do all they can to prevent the destruction of the famous city.
Can the children persuade the Trojans to reject the Greeks' gift of the Wooden Horse or will it prove impossible to change the course of history?
