Travel back in time to the days of the Roman Empire and join Tranio, the son of an actor, and his friend Livia, the baker's daughter, in witnessing the eruption of Mount Vesuvius in AD79. Tranio, like most Roman boys, likes to watch whatever is going on: tradesmen selling their goods, ships unloading their exotic cargoes, politicians making speeches in the forum. But one hot August day a very different scene unfolds. The ground begins to shake, the sky darkens. People run gasping for air. Heading for the harbour, Tranio and his friend Livia hide on a boat and witness one of the most terrifying moments in recorded history-the eruption of Mount Vesuvius and the destruction of their beloved city, Pompeii.
