A new addition to the multiple New York Times best-selling Ring of Fire series! It's springtime in the Eternal City, 1635. But it's no Roman holiday for uptimer Frank Stone and his pregnant downtime wife, Giovanna. They're in the clutches of would-be Pope Cardinal Borgia, with the real Pope - Urban VII - on the run with the renegade embassy of uptime Ambassador Sharon Nichols and her swashbuckling downtime husband, Ruy Sanchez de Casador y Ortiz. Up to their necks in papal assassins, power politics, murder, and mayhem, the uptimers and their spouses need help - and they need it quickly!
