"No one in the bustling city of Pompeii worries when the ground trembles beneath their feet. The beast under the mountain Vesuvius, high above the city, wakes up angry sometimes--and always goes back to sleep. But Marcus is afraid. He knows something is terribly wrong--and his father, who trusts science more than mythical beasts, agrees. When Vesuvius explodes into a huge cloud of ash and rocks that fall from the sky like rain, will they have time...

Annie and Jack visit Pompeii just as the volcano is about to erupt and must find a Roman scroll before everything is buried in ash.
