Twenty-two-year-old James Gould arrives in Occupied Naples in 1943, where his duties include dissuading Allied soldiers from marrying their beautiful Italian girlfriends, and his diet includes little more than spam fritters and warmed-up rations. The girls of Naples, however, soon arrange for a beautiful young country girl to join his staff as a cook. Under the twin influences of Italian food and Italian passion, James has only just realised that his heart is more important than his orders, when an eruption of Vesuvius sets in motion a series of epic events that will change their lives for ever.
