This is the third book in the arc dealing with the Uptimers in Italy and the fate of the Catholic Church. Galileo Affair starts out with... well... the Galileo Affair. And also there was that foiled assassination attempt on Pope and nurse/ambassador Sharon Nichols falling in love with a guy older than her dad.
In Cannon Law, one of the uptimers, Frank Stone, with his newlywed bride start up a CoC/pizza parlor in Rome, Sharon marries "Feelthy Sanchez," and then Cardinal Borgia ruins everyone's day by taking over the city, killing more than a dozen other Cardinals, and declaring himself the new pope.
Here in the Papal Stakes, Harry Lefferts and his wrecking crew are in town to save Frank Stone and his pregnant bride. Sharon Nichols is leading to protect the legitimate Pope from Borgia's assassins until they can get him out of town. But does he even want to skip town? And is it possible that Lefferts and Co. have finally met their match? Bullets fly and the body count piles up at the end of this book, but there's a lot of plot, preparation, philosophy, and pontificating that must happen. For those who prefer middle grade books like Hunger Games, Twilight, or Harry Potter, this part probably isn't for you and you will get bored waiting for "real stuff" to happen. For those who enjoy real fiction, this book is definitely a worthy entry into the Ring of Fire series.
