It is Rome, 1635, and Grantville's diplomatic team, headed by Sharon Nichols, is making scant headway now that it has become politically inexpedient for Pope Urban VIII to talk to them any more. Sharon doesn't mind, she has a wedding to plan. Frank Stone has moved to Rome and is attempting to bring about the revolution one pizza at a time. Cardinal BoIja is gathering votes to bring the Church's reformers to a halt in their tracks, on the orders of the King of Spain. Meanwhile, trouble is brewing in the streets, shadowy agitators are stirring up trouble and Spain's armies are massed across the border in the Kingdom of Naples, Cardinal Barberini wants the pamphleteers to stop slandering him and it looks like it's going to be a long, hot summer. Except that Cardinal Borja has more ambitions than his masters in Madrid know about, and has the assistance of Spain's most notorious secret agent to bring about his sinister designs.
