It is a.d. 79. The Roman world is reeling from the eruption of Mount Vesuvius. Hundreds of refugees are living in a makeshift camp, trying to come to terms with what has happened. Then even more tragedy strikes: the camp’s children begin to disappear. Flavia Gemina and her friends Jonathan, Nubia, and Lupus are determined to find out more and start to investigate a powerful and charismatic man known as the Patron. A dangerous trail leads them to the caves and grottoes of Sorrento, where they encounter pirates, slave dealers—and possible death.
